- Digital Transmitter:
A DFB laser diode is employed for upstream transmission at OC-24 (1244Mbps). The optical transmitter includes a back facet
photodetector to monitor laser power for APC control.
- Digital Receiver:
An APD with TIA is employed for downstream data reception at OC-48 (2488Mbps). A post amplifier is also included for CML
output compatibility.
- Analog Receiver:
1GHz forward path video (CATV) receiver with multiple gain stages, automatic gain control (AGC) and status indicators.
