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-887 + 7 dBm FIBT-S3A-810 + 10 dBm
FIBT-S3A-888 + 8 dBm FIBT-S3A-811 + 11 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.
