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.

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-ofthe-art FM video modulator 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 850nm, 1310nm, or 1550nm electro-optics are incorporated to achieve the performance levels cited below. 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! Each unit is built in a rugged enclosure that offers excellent EMI/RFI shielding. SPECIFICATIONS Min. Typical @ 25˚C Max.
