Optical TRX 270 Mbit/s

The modules provides a reliable digital Video/Audio communication for satellite earth stations and broadcast link applications over optical fiber (up to 50 Km distance) to comply the features required for transmitting serial digital signal 270Mb/s ASI EN50083-9 and SDI BT656-3 standards.
In the transmitter module, after equalizing and re-clocking the digital input signal, returns via two active loop-through outputs, modulates the intensity of laser-module with an optoelectronics feedback loop to maintain a constant optical output power.
The optical signal is coupled into a single mode fiber pigtail with an optical connector.
In the receiver module, after receiving the optical signal, feed from multimode pigtail fiber, converted to electrical with sensitive PIN photo diode,

pre-amplified with low noise amp, automatic gain controlled, then re-clocked with precise P.L.L. to drive two digital SDI/ASI outputs.
Indicators for loss of input and Tx/Rx status, laser current measuring point are located in the front panel. BNC for digital input/output and DIN connector FOR optical in/out are located in the rear panel.
