Coherent Receiver, Bench-top, IQ/QPSK/xQAM/BPSK Multi-Format


The coherent receiver is an O/E evaluation equipment designed to convert DP-QPSK / BPSK / xQAM optical data to differential electrical signals.  It consists of integrated coherent receiver module, power and control board. The receiver offers several user-adjustable characteristics such as RF gain, PD bias, and mode of operation, Auto Gain Control (AGC) or Manual Gain Control (MGC) and is ideally suited for a variety of applications. Additionally, the output voltage swing adjustment is available.
