Реферат: A coherent receiver (10) includes a receive signal, SIG, path (14) including i) an input configured to connect a receive signal, ii) one or more signal paths connected to the input and to one or more optical hybrids (32), and iii) at least one variable optical attenuator, VOA (12); a local oscillator, LO, signal path (16) including an input configured to connect to an LO and the one or more optical hybrids (32); and a VOA-induced phase change compensation mechanism that reduces any VOA-induced phase change in a SIG-LO beat signal due to the at least one VOA (12).
