Blonder Tongue’s Fiber Optics 

Whether you are considering consolidating headends, expanding to new areas, providing ingress-proof return signals, 

transporting remote studio feeds, or stretching L-band signal further than ever before, Blonder Tongue has a fiber optic 

solution to suit your needs. Blonder Tongue’s combination of engineering expertise and versatile product line make us an 

ideal supplier for all of your fiber optic needs. Our product line is broken down in to four major areas: 

TRAILBLAZER: Broadband 80 & 110 Channel Links 

RETRO-LINX: Baseband and Limited Broadband 

TWIN STAR: L-band 

FIBER CONNECT: Accessories 

TRAILBLAZER 

The TRAILBLAZER line is Blonder Tongue’s broadband fiber optic distribution solution. The line consists of transmitters, 

receivers, and integrated receiver/distribution amplifiers to meet any distribution requirement. Full 860 

MHz bandwidth fiber optic links are available to provide up to 110 VSB/AM channels (or 80 VSB/AM channels plus 

30 digital channels) at a distance of over 20 km. These high quality links will provide excellent RFI free performance 

for headend distribution to apartment complexes, campuses, hospitals, campgrounds, and pocket deployment 

of interdiction technology. Using a TRAILBLAZER transmitter in conjunction with our line of couplers will 

enable you to reach more destinations at once. Don’t hesitate to call on our systems engineering group to help 

you design a system. 

RETRO-LINX 

The RETRO-LINX line is comprised of three different product areas to fulfill many specialty applications. The three 

product areas are: limited broadband, video/audio/audio, and video only. The limited broadband area has 5, 10, 

15, or 25 channel links available. You can use these links to move RF channels from your sub-band return path 

on to fiber, increasing the quality of the signal, as well as the range. The video/ audio/ audio area can eliminate 

the headaches of trying to get a remote feed back to the headend via the existing coaxial plant, or point to point 

microwave. This product provides clean, ingress-proof studio feeds that can go the distance on either single mode 

or multimode fiber. The FM video only links enable remote monitoring options through your existing fiber plant. 

The links are available for either single mode or multimode fiber. The single mode versions can go out to 70 km, 

and the multimode can go up to 15 km. 

TWIN STAR 

The TWIN STAR line is Blonder Tongue’s L-band fiber distribution solution. The line is comprised of single and 

multiple output transmitters and receivers. These multi-output units enable distribution of L-band signals farther 

than ever possible with coaxial cable. The compact single transmitters and receivers can be used to bring signals 

back to the headend from remote downlink sites. The multiple output transmitters and receivers are designed with 

the MDU build in mind. The transmitters are available with 8, 12, and 16 optical outputs, while the receivers are 

available in 8, 16 or 24 RF output versions. This means that you can easily get signal to 1,536 receivers from one 

dish! The receivers are versatile in the fact that they diplex the CATV signal and the L-band signal together to provide 

a single wire to the home solution. The receiver will pass the sub-channel return signal and can also be line 

powered from the CATV signal.

FIBER CONNECT 

The FIBER CONNECT line fulfills all of your accessory needs, enabling Blonder Tongue to be your one-stop shop 

for fiber optics. Our industry standard fiber management boxes allow for safe, convenient routing of your fibers at 

the headend. Blonder Tongue has a wide variety of jumper cables, varying in lengths from 1m to 50m. The cables 

are available in several popular, industry connector styles to ensure a fit with your equipment. Every installation is 

different, that is why we carry a diverse line of couplers. The couplers are available from two to eight outputs, in 

stand alone, LGX, or 19" rack mounted versions. The two and three port units come in a variety of splitting ratios to 

enable custom configurations. The newest addition to the FIBER CONNECT line is the Wave Division Multiplexer 

(WDM), which allows two-way optical traffic with in the same optical fiber. The unit can also allow two different signals 

to go in the same direction at the same time with out interfering with each other. Another addition to the line is 

the fixed optical attenuator. An optical attenuator can reduce the signal level being provided to a receiver to prevent 

distortion from overdriving. The final crucial element to the line is being able to test the system. In one rugged, convenient 

kit we provide all the tools that are necessary to test the basic performance of the system. 

Whether you are considering consolidating headends, expanding to new areas, providing ingress-proof return signals, 

transporting remote studio feeds, or stretching L-band signal further than ever before, Blonder Tongue has a 

fiber optic solution to suit your needs. Blonder Tongue’s combination of engineering expertise and versatile product 

line make us an ideal supplier for all of your fiber optic needs.

The FIBT series of transmitters provides a robust system for 

transferring 80 or 110* channels of VSB/AM modulated signals 

over a single mode optical fiber. The system provides for 

up to 860 MHz of usable bandwidth for video signals stacked 

at 6 MHz intervals. A low loss single mode optical fiber (e.g. 

0.5 dB/km) will allow full channel loading to beyond 20 km 

while maintaining good CNR, CSO, and CTB specifications. 

(*The 110 channel system can also transfer 80 CATV 

channels along with 30 digital QAM channels in the upper frequency range.) 

The FIBT-S3A series transmitter uses a high-power, low noise 1310 nm distributed feedback (DFB) laser diode. An optical 

isolator protects the laser from optical reflections in the transmission path. This ensures high CNR, consistent performance 

in all installation scenarios, and excellent linearity. The transmitter is configured for EIA 19" wide rack mounting 

with a height of 1.75". The chassis can be powered to operate from 110 VAC or 220 VAC. 

The optical output levels are as follows: 

MODEL OPTICAL OUTPUT MODEL OPTICAL OUTPUT 

FIBT-S3A-886 + 6 dBm FIBT-S3A-819 + 9 dBm 



FIBT-S3A-812 + 12 dBm 

The transmitters contain LED status indicators that allow the link’s status to be quickly assessed locally. 

POWER INDICATOR (Green LED): The LED will be green when the unit is receiving AC power, and off 

when the unit is not receiving power. 

RF INPUT (Tri-color LED Green/Amber/Red): When the LED is green, the signal is at optimum input levels. 

When the LED is amber, the RF input signal has dropped to 

insufficient levels, and when the LED is red, the signal is overloading 

the unit. 

COOLER STATUS (Bi-color LED Green/Red): When the LED is green the laser cooler is functioning properly, and 

the laser temperature is stable. It is normal for this LED to change 

from red to green in the first ten seconds after power has been 

applied to the transmitter. If the unit turns red any other time, the unit 

should be turned off immediately. 

LASER STATUS (Bi-color LED Green/Red): When the LED is green the laser is initialized and operating normally. 

It is normal for this LED to change from red to green in the first ten 

seconds after power has been applied to the transmitter. If the unit 

turns red any other time, this may indicate a laser failure. 

All of these status monitors can be monitored remotely via the D-Sub 9-Pin connector on the rear of the unit.

The MIBT/SIBT-S3A-210 series fiber optic transmitters provide a 

high-quality system for transferring up to ten video channels over single 

mode optical fiber with complete EMI immunity. The units offer 

exceptional analog bandwidth from 5 MHz to 250 MHz allowing transmission 

of all sub-band channels, low-band channels, FM channels, 

and mid-band channels. The lowest high-band channels may also be 

accommodated. The best performance will be achieved when the 

channel plan is designed to contain all of the channels within a single 

octave of bandwidth. The system can transmit signals from a VCR, 

camcorder or cable television feed over a distance of 10 km on one single 

mode fiber. 

It is very important to provide the proper RF signal level to the transmitter. 

The transmitter includes a tri-color RF level indicator that allows 

the optimum RF input level to be quickly and positively identified. A 

state-of-the-art 1310 nm single mode laser and PIN detector are used to achieve the performance levels cited. This 

product is recommended for use with single mode fibers only. A minimum fiber bandwidth of 500 MHz is required.

APPLICATIONS 

The MIBT/SIBT-M3T-25 series transmitters, used with the MIBR/SIBR M3T-25 

receivers, provide a high-quality system for transferring up to five video channels 

per multimode fiber with complete EMI immunity via fiber optics. The units offer 

exceptional analog bandwidth from 5 MHz to 250 MHz, allowing transmission of 

all sub-band channels, low-band channels, FM channels, and mid-band channels. 

The lowest high-band channels may also be accommodated. 

The best performance will be achieved when the channel plan is designed to contain 

all of the channels within a single octave of bandwidth. When used in conjunction 

with a VCR, a camcorder, or cable television feed, the system can transmit 

TV channels 2 through 6, along with their sound carriers, over a distance of 3 

km or more at 1310 nm, over a single 62.5/125 µm multimode fiber. 

The carrier-to-noise (CNR) ratio is typically 47 dB at low optical loss. The units 

also offer exceptional performance at lower channel loadings. This product is 

recommended for use with 62.5/125 µm fibers only. A minimum fiber bandwidth of 

250 MHz is required.

The MIAT/SIAT-M3T/M8T/S3T/S5T transmitters, used with 

the MIAR/SIAR-M8R/U4T-3 receivers, provide a high-quality 

system for transferring baseband video signals and stereo 

audio signals with complete EMI immunity via fiber optics. 

The transmitters accept one video and two unbalanced (600 Ω 

or 10 kΩ) audio inputs and combine them for transmission over 

a single optical fiber. 

The receivers accept the composite optical signal and convert it 

to a video and two unbalanced (600 Ω or 10 kΩ) audio outputs. 

This FM video/stereo audio fiberoptic link offers near 

studio-quality performance in low-to-moderate optical loss applications. 

Available for use with either single mode or multimode fiber, the link uses a state-of-the-art FM video modulator/demodulator 

operating at a center frequency of 60 MHz, 6.0 MHz and 6.8 MHz audio carries to achieve this performance. 

Because of the FM technique employed, no user adjustments are required over the full optical loss range. While optimum 

performance is achieved with an RS-250 C video input and 1-Volt RMS audio inputs, the output level tracks the 

input level over the full optical loss range. Used with a good quality optical fiber (0.5 dB/km @ 1310nm & 1000 MHz 

km), the multimode version will function over more than 15 km of fiber, and the single mode version will function over 

more than 70 km!

NOTES 

1) All optical power levels are average values. The receiver includes a Loss-of-Signal indicator that is green when there is sufficient optical input and turns red when there is a loss of sufficient optical input. 

Because the LED is always lit, it also serves as positive indication that the unit is receiving power. 

2) Most parameters are relatively unaffected by varying temperature. The transmitter output power does drift considerably with temperature. In general, optical output drops at higher temperatures and 

increases at lower temperatures. (Values for this specification are at 25 ˚C) 

3) Multimode versions of the MIAT/SIAT-31 are optimized for use with 62.5/125 µm fiber, and all transmitter power levels are measured through 1 meter of 62.5/125 µm fiber. Most popular multimode fiber 

sizes including 50/125 µm, 85/125 µm, and 100/140 µm can also be used. Following are the typical optical link budgets with different size fibers. 

850 nm Model: ** Bandwidth limited typically. 1300 nm Model: Bandwidth limited typically. 

Fiber Type Max Loss Typ. Distance Correction Factor Max Loss Typ. Distance Correction Factor 

50/125 µm 12.0 dB 1.5 km 6.0 dB 17 dB 12 km 1 dB 

62.5/125 µm 15.0 dB 1.5 km 3.0 dB 18 dB 8 km** O dB 

100/140 µm 20.0 dB 1.0 km** -2.0 dB 19 dB 2 km** -1 dB 

4) The signal-to-noise performance is given at three ranges of receiver input power. This allows the user to accurately predict how the link will perform in a given application. All signal-to-noise values are 

NTSC weighted using the unified weighting network per RS-250C and limited to 4.2 MHz. 

5) Single mode versions of the MIAT/SIAT-31 are optimized for use with single mode fiber, and all transmitter power levels are measured through 1 meter of 9/125 µm fiber. Most popular multimode fiber 

sizes including 50/125 µm, 62.5/125 µm and 100/140 µm can also be used. Operating distance will be substantially reduced due to the limited bandwidth of these fibers compared to single mode fiber. 

6) Supply voltage is DC ranging from + 12 Volts to + 15 Volts. Operation at higher voltage is possible, but the upper operating temperature of the part should be derated 5 ˚C for every Volt over + 15 Volts. 

The units will tolerate moderate amounts of ripple, but this should not exceed 0.5 Volts peak-to-peak. It is critical that the supply voltage NEVER drops below + 12 Volts for any part of the waveform. 

Voltages below + 12 Volts will cause the internal voltage regulators to lose regulation which will disrupt the operation of the unit and cause unpredictable results. The input of the unit is filtered with approximately 

220 pF of capacitance. Power supplies with fast-blow fuses may trip when powering the links. 

7) Be sure to compute your fiber bandwidth (end-to-end) as well as attenuation. This often gets overlooked by system designers. The fiber bandwidth is often quite low when 850 nm is used. 

8) All specifications shown are met with an RS-250C video signal. A smaller input level will result in reduced signal-to-noise ratio while a larger input level will result in degraded differential gain and phase 

performance. 

9) Output level automatically tracks the input level within the specified tolerance regardless of optical loss.

Fiber Optic FM Video Receivers MIAR-11/SIAR-11 Series 

The MIAR/SIAR-U8T/U4T-11 FM Fiber Optic Receivers provide a high-quality system for 

transferring baseband video signals with complete EMI immunity via fiber optics. This universal 

FM video fiber optic link offers near studio quality performance in low-to-moderate 

optical loss applications. Available for use with either single mode or multimode fiber, the 

link uses a state-of-the-art FM video modulator/demodulator operating at a center frequency 

of 60 MHz to achieve this performance. Because of the FM technique employed, 

no user adjustments are required over the full optical loss range. Optimum performance 

is achieved with an RS-250 C video input. The output level is designed to track the 

input level over the full optical loss range. The link can be used for monochrome, 

NTSC color, PAL and HDTV because it has exceptional bandwidth, over 15 MHz. 

State-of-the-art 850 nm, 1310 nm, or 1550 nm electro-optics are incorporated to achieve 

the performance levels cited below. Used with a good quality optical fiber (0.5 dB/km @ 

1310 nm & 1000 MHz km), the multimode version will function over more than 15 km of 

fiber, and the single mode version will function over more than 70 km! Each unit is built in 

a rugged enclosure that offers excellent EMI/RFI shielding.

Blonder Tongue’s FILT series L-Band fiber optic transmitters provide a cost-effective method of transporting 

L-Band signals to satellite receivers with the EMI immunity and superior performance inherent 

in fiber optic links. 

The FILT-S3A-2050 is a single output transmitter that can be used for transporting LNB signals from 

a TVRO site to a headend facility as an alternative to the loss and slope associated with coaxial links. 

The FILT-S3A-2050, along with Blonder Tongue’s L-Band distribution amplifiers, optical couplers and 

L-Band passive devices can also be used to transport L-Band signals within MDU installations as part 

of a custom designed ‘single-wire’ distribution system. 

The FILT-S3A-2050 provides full 950-2050 MHz L-band satellite distribution over a single fiber optic 

cable with enough optical power to drive several remote fiber optic receivers. These high quality links 

will provide excellent RFI free performance for distribution to garden style apartment complexes, and 

high rise buildings. Our engineers will assist you in designing your L-Band optical networks for peak 

performance. 

Special ‘stacked’ LNBFs are available to provide both satellite polarities on a single cable. The ‘single 

wire’ system, including one or more FILR series receivers, can provide one coaxial output to feed 

satellite receivers in a headend or apartment unit. In MDU applications, each satellite receiver 

is connected to a ‘Subscriber Unit’ that responds to the receiver’s tuning instructions and automatically ‘unstacks’ the 

polarities in order to provide seamless service to the viewer. 

Existing CATV or MATV channel lineups can be multiplexed onto the MDU subscriber’s coaxial cable drop outside 

the unit to maintain a ‘single wire’ solution for all entertainment services. Blonder Tongue also provides traditional 

AM/VSB fiber optic links that can distribute your CATV signals to your MDU units via fiber, creating a complete high 

performance optical network. 

Blonder Tongue’s combination of engineering expertise and versatile product line make us an ideal supplier for all 

your fiber optic needs. Whether you are connecting TVRO antennas to your headend, reaching new buildings from 

a master headend, building a brand new MDU satellite distribution system or overlaying satellite services onto an 

existing CATV/MATV system Blonder Tongue has the solution.

Blonder Tongue’s FILT-S3A-2050-8/12/16 series of fiber 

optic transmitters allow the operator to distribute DTH/DBS 

signals from a single satellite dish to multiple locations via 

single mode fiber. The transmitter is manufactured in 

three versions, 8, 12, and 16 outputs, to accommodate 

different size installations. 

The unit features automatic gain control (AGC) on the satellite input to help ensure optimum input levels. The AGC 

helps ensure consistent system performance by increasing amplification to overcome degradation due to weather 

changes. The performance of the link can be quickly determined either locally or remotely. The unit features an RF 

input indicator LED. When the LED is red, the satellite input signal level is too low. the power indicator LED will be 

green when the unit is receiving AC power, and off when the unit is not receiving power. Status can be monitored 

remotely because the unit has a TTL monitor with two contact terminal strip. The unit can be interfaced with any type 

of hardware that has a 5V detection circuit (5V to 0V = Alarm). All three versions of the transmitters are in a single 

height, 1.75” high, rack mountable, aluminum chassis for easy installation into any headend. LNB power is multiplexed 

on the RF input connector, eliminating the need for external power inserters.

FILN Series L-Band Fiber Optic Receivers 950-2050 MHz 

Blonder Tongue’s new FILN multi-output L-band receiver is a breakthrough in hybrid fiber/coax (HFC) optical node technology. 

The unit combines the superior distribution attributes of several key functions into a single package. These are: 

Satellite signal fiber receiver 

Professional quality L-band amplifier 

Bi-directional CATV network amplifier employing trunk line grade hybrid amplifier modules 

Plug-in equalizers and attenuators for greater CATV input signal management, creating design flexibility 

CATV and satellite signal multiplexing and splitting networks with up to 24 residential outputs 

Return path management and amplification (10-40 MHz) 

Internal power supply to support powering from the network 

Fiber Receiver 

The unit provides L-band DTH signal for up to 24 residential outputs, from one fiber input. There is an LED indicator on the 

optical input of the unit to indicate proper input level. There is also an LED on the L-band output to indicate the optimum output 

level. High output signal levels are provided at each output to overcome the loss of both long drop lengths, and splitters 

required to serve multiple viewing location. 

CATV Network Amplifier 

The unit accommodates a wide range of CATV input levels, making it more forgiving to existing CATV conditions and allowing 

for greater design flexibility. This is accomplished by the use of simple plug-in attenuators and equalizers to condition the input 

signal prior to amplification and splitting. The network amplifier is specifically designed to handle larger quantities of analog 

programs, especially those that are combined with QAM digital signals, as set out by the NCTA 110 channel specifications. 

The unit multiplexes the bi-directional CATV signals with the satellite signals at each of the 24 outputs creating a “True Single 

Wire” distribution solution. 

The product was designed to distribute DTH/DBS in the MDU environment. The high output levels allow for long cable runs 

and splitters, to support multiple viewing locations.

The Blonder Tongue Fiber Optic Test Kit is used to trace, identify, and troubleshoot single mode 

or multimode optical fiber systems. The kit consists of a OSL probe, a light source/transmitter, a 

battery charger, operating batteries for both units, one 3-meter jumper cable with ST-ST connectors, 

Optical Power Meter - Dual Wavelength and a rugged, sealed, insulated carrying case. 

The OSL probe is an ultra-miniature troubleshooting tool that detects 1300 nm signals injected into 

a fiber. The compact unit is powered by one AA alkaline battery (provided) and provides both an 

audible tone and visual (red LED) indications of signal detection. 

The Fiber Optic Test Kit light source/transmitter provides an economical means of injecting light 

into single mode and multimode fibers. The light source/transmitter is mounted in a small, highly 

portable, plastic enclosure and offers stabilized optical output that is user-adjustable over a 10 dB 

range. The output may be selected for a 500 Hz continuous tone or a gated (@ 1Hz) 500 Hz tone, 

creating a unique signal that may be easily identified by the probe. This unit is powered by four 

AA NiCd rechargeable cells that recharge in six hours typical using the battery charger (provided). 

The optical power meter allows direct measurement of optical signals throughout the system.

Blonder Tongue’s WDM-1315 allows a single mode fiber to be used to simultaneously transmit 

two optical signals of different wavelengths. The unit at the transmit end combines a 1310 nm 

signal and a 1550 nm signal for output on to one single mode fiber. The unit at the receive end 

separates the two signals onto two optical fibers with minimal crosstalk and low loss. This 

allows ‘true two-way traffic’ in one single mode fiber, creating an optical return path. The WDM- 

1315 can also allow two signals to be sent in the same direction on one fiber

FIBT DESIGN TOOL 

1. What is the acceptable C/N you want to see at the output of the fiber optic receiver? dB (#1) 

2. Determine the optical input needed at the receiver to maintain your C/N from above. Find the C/N figure on 

the Y axis on the chart below. Follow that figure across until you come to the curve that corresponds to your 

channel loading. Follow this intersection down to the X axis to determine the optical input level. This is the level 

that you need to hit the receiver with in order to maintain the C/N that you picked in Step #1. dBm (#2)

You should round this number up to the next dBm to build in a margin of error to cover any unseen items 

in the link budget.

5. Determine the RF input level needed at the transmitter. Find the channel loading figure on the X axis on the chart 

below. Follow that figure up until you come to the curve that corresponds to the series transmitter you are using. 

The top curve is the 7404 Series, the bottom is the 7403 Series. Follow this intersection across to the Y axis to 

determine the RF input level. This is the level that you need to hit the transmitter with in order to ensure a quality 

signal. This is the optimal RF level for your channel loading configuration. We will also use this number to 

predict the RF output level of the link dBmV (#5)

Fiber Optic System Survey 

This technical bulletin explains what to ask customers about their 

fiber optic systems in order to do a system design. 

N order to design a fiber optic system for a customer, certain key pieces of data 

must be known about their existing system or construction plans. We have listed 

the main components in this bulletin. 

Overview 

Whether a fiber optic customer inherits a fiber cable system or components or 

contracts to have them installed, there a critical parameters that must be known in 

order to do the optical and RF design for that system. Questions regarding the type of 

fiber cable being used, how many fibers have been laid, whether the fibers are 

homerun or tree-and-branch style and what connector types were used are examples. 

Fiber Optic Survey 

These questions should provide the necessary data to design your fiber system. 

1. What type of fiber cable is being used? Single mode or Multimode? 

2. Is there a separate fiber from the headend to each location or a single 

fiber or cable from the headend that passes by each location serially? 

3. Is the fiber cable connectorized and which connectors have been used? 

(FC, SC, ST, mini-SC etc.)*see photo 

4. Do the fiber ends terminate in a WIC cabinet or fiber management box? If 

so, are the connectors on the front panels of the box accessible? 

5. Are the individual fibers to the end locations labeled and/or color-coded? 

1

6. Do you have a map of the fiber routing? Does the fiber run uninterrupted 

between locations or are there splice junction boxes, repair splices or hub 

rooms where the fiber transitions between buildings? 

7. Has the fiber ever been tested and if so do you have loss figures or OTDR 

printouts? 

8. Are you using dark fibers that are part of an existing system? 

9. What function do the fibers perform that are in use? Ethernet? Video? 

10. What color jacket does the fiber you plan to use have? Orange? Yellow? 

11. What color sleeve does the connector have that you plan to use? Green? 

White or Black? Blue? 

12. If you plan to rack mount any fiber equipment, what width are the existing 

racks? Do you have permission to use them? Are there electrical outlets 

available? 

13. What is the average ambient temperature of the room where your active 

fiber equipment will be housed? Will it be over +40 degrees C.? 

14. How many channels of video do you plan to transport via your fiber? 

15. Is this an AM/VSB (CATV/MATV) application or L-Band (950-1450 MHz 

digital transport) application? 

16. Do you plan to use existing optical couplers to split the fiber signal to 

feed multiple locations? If so, do you have the model numbers and loss 

data of the couplers including their wavelength? 

17. Will you require fiber jumpers to connect transmitters to couplers, 

equipment to patch panels, patch panels to outbound fibers etc? If so, 

how long do they need to be and what type of fiber and connectors will be 

required? 

18. Will the fiber signal require amplification after it is received? (what signal 

level do you need at the receive sites to feed the appropriate 

equipment/units?) 

19. Will you be splitting the optical signal in locations other than 19” rack 

mount headends or hubs? If so, what are the environmental conditions? 

20. Will your optical receivers be collocated with AC power sources? 

21. What are the lower and upper frequency limits of your source channels? 

22. Do you own any fiber test equipment? OTDR? Power Meter? 

23. Are you planning to use any other existing fiber equipment besides cable 

or patch panels? Transmitters? Receivers? Do you have the data sheets 

and specifications for this equipment?

The recommended RF input level is shown in Figures 3.2 and 3.3. Actual units do vary several dB’s from these curves. 

Each transmitter has a label such as the one shown in Figure 3.4 that gives the exact levels for that particular transmitter. 

The carrier levels should be closely matched to ensure consistent performance on all channels. In all cases, set the composite 

RF input level so that the RF Level Indicator LED is green. Note that the RF indicator LED only operates for rated 

channel loading and a flat input spectrum.

Figure 1.4 - Optical Input (mW) vs. Power Meter Output (Volts) 

Figures 1.3 and 1.4 show the response of the built-in optical power meter circuit in both dBm and mW. The dotted line 

shows the typical, expected response of the circuit. Because the accuracy of the reading is affected by the variable mating 

loss of the input optical connector, there is an error band of ±0.5 dB represented by the solid lines. For instance if the optical 

input power was +6 dBm, the circuit would ideally output +5.0 Volts. Considering the possible errors introduced by the 

optical connector, the reading could be as low as +4.5 Volts or as high as +5.4 Volts. Note that the circuit outputs a voltage 

of +1.0 Volts with no light input. 

The 7412-PA incorporates an optical attenuator that allows the user to adjust the incoming optical signal to the optimum 

input of 2 mW (+3 dBm). This attenuator should be used as follows: Align the red dot on the top of the attenuator with the 

red line painted on the outer fixation ring. Next take a reference reading from pin J2-4 to determine the optical power 

reaching the receiver. With the red dot and line aligned, slowly rotate the inner control ring of the attenuator until the voltage 

on pin J2-4 reads 3 Volts which is equal to the optimum input voltage of 2 mW (+3 dBm). (An attenuator adjustment 

tool is included.) After the desired attenuation is reached, use the adjustment tool to turn the outer fixation ring 45° in 

either direction to lock the control ring in place. NOTE: Do not try to rotate the control ring unless the red dot and the red 

line are aligned. Do not turn either ring to their end points, or the attenuator may break.

OPERATING INSTRUCTIONS 

1) Connect the optical fiber to the transmitter and the receiver. Be sure that the fiber has continuity and less than the 

maximum allowable optical loss. Also be certain that the fiber is the proper size. This product can only be used with 

single-mode fiber. The input power to the Rx must be less than +4.5 dBm. The units will not work back-to-back. The 

optical input level to the Rx can be ascertained by checking the color of the LOS indicator LED on the Rx. 

Red LED = Too much optical power 

Green LED = Correct optical power level 

Yellow LED = Not enough optical power 

2) Connect the RF source (VCR, camcorder, cable television, etc.) to the RF analog input on the transmitter. 

3) Connect the RF analog output on the receiver to the monitor input. The monitor input should present a 75 Ohm 

impedance. 

4) Connect the AC power cord to the back of the transmitter. When power is first applied, the “Power” and “RF Input 

Level” LED’s should light green. The “Cooler Status” and “Laser” LED’s will light red or change from red to green 

within the first ten seconds of initialization and then change to green to indicate normal operation. If the “RF Input 

Level” LED is red, this means the RF level is too high. Decrease the input level until the LED is green. If the “RF 

Input Level” LED is yellow, this means the RF level is too low. Increase the input level until the LED is green. 

WARNING: OPTICAL LASER RADIATION IS PRESENT AT THE OPTICAL CONNECTOR WHEN THE UNIT 

IS ACTIVATED. AVOID DIRECT EYE EXPOSURE TO THE BEAM. 

5) Connect power supply to the receiver. The power supply must be from +12 to +16 Volts DC. It is critical that the supply 

voltage never drops below +12 Volts. If the voltage drops below +12 Volts, the link may not operate. When 

power is applied and the link is operational, the “LOS” LED should light green. 

WARNING: OPTICAL LASER RADIATION IS PRESENT AT THE OPTICAL FIBER THAT ATTACHES TO THE 

RECEIVER’S OPTICAL CONNECTOR WHEN THE UNITS ARE ACTIVATED. AVOID DIRECT EYE EXPO- 

SURE TO THE BEAM. 

6) Apply power. The units are now fully operational. The incoming optical signal is adjustable when using the 7412-PA. 

See Adjusting the Optical Attenuator for details on that adjustment. No other user adjustment or attention is required. 

See Section 4.0 of the Instruction Manual for instructions on maintaining and cleaning the link. See Section 5.0 the 

Instruction Manual for information on troubleshooting. 

Section 2 

31

ADJUSTING THE OPTICAL ATTENUATOR (7412-PA ONLY) 

1) Align the red dot on the top of the attenuator with the red line painted on the outer fixation ring. 

2) Take a reference reading from pin J2-4 to determine the optical power reaching the receiver. 

3) With the red dot and line aligned, use the attenuator adjustment tool included to slowly rotate the inner control ring 

of the attenuator until the voltage on pin J2-4 reads 3 Volts which is equal to the optimum input voltage of 2 mW (+3 

dBm). 

4) After the desired attenuation is reached, use the adjustment tool to turn the outer fixation ring 45° in either direction 

to lock the control ring in place. NOTE: Do not try to rotate the control ring unless the red dot and the red line are 

aligned. Do not turn either ring to their end points, or the attenuator may break. 

TROUBLESHOOTING 

Commercially available test equipment such as a Blonder Tongue’s Fiber Optic Troubleshooting Kit (Stock No. 7491) are 

effective tools for locating problems with the fiber optic cables. The FOTK can also be used to verify that the transmitter is 

indeed putting out light. Other common problems include using a transmitter as a receiver and vice versa, lack of continuity 

in the optical fiber, lack of power (or reversed power), or improper input levels. Note that the transmitters and receivers 

are designed to work with a 75 Ohm system. A number of indicator LED’s are available to assist in trouble-shooting the 

link. These allow the user to quickly assess the nature of any major unit malfunctions. If problems persist contact Blonder

All specifications shown are met when the RF input levels comply with the values shown in Table 1. A smaller RF 

input level will cause reduced carrier-to-noise ratio which may produce a snowy picture. A larger RF input level 

will cause increased distortion between channels which may produce irritating interference bars or patterns in the 

picture. Table 1 shows the optimum (maximum without distortion) RF input level in four different units: dBm, 

mVRMS, mVP-P and dBmV. Table 1 also shows the typical CNR that can be achieved with the link at 0 dB optical 

loss. The CNR is specified for a bandwidth of 4.0 MHz. At 1310 nm, the loss is typically only 0.5 dB/km, so the 

listed level of performance could be expected at distances shorter than 0.5 km. As the optical loss increases, the 

CNR will degrade as indicated in Figure 3. Note that it is important that all channel amplitudes be closely 

matched for the best performance. Figure 1 shows the same information graphically.

Commercially available test equipment such as Blonder Tongue’s FOTK Fiber Optic Troubleshooting Kit are effective 

tools for locating problems with the fiber optic cables. The FOTK can also be used to verify that the transmitter is 


in the optical fiber, lack of power (or reversed power), or improper input levels. The transmitter is optimized to 

accept a 1-Volt sync-to-white video input signal and two 1-Volt RMS audio signals. Larger inputs will introduce nonlinearities 

or interfere with function. Note that the transmitters and receivers are designed to work with a 75 Ω video 

system and a 600 Ω or 10 Ω audio system. If problems persist consult Blonder Tongue’s Systems Engineering 

Department.
