Device and methods for real-time polarization-dependent loss monitoring at coherent transceivers. In one embodiment, there is provided a method of monitoring a polarization dependent loss (PDL) of a signal during transmission through an optical communication link, the method comprising: receiving the signal by a coherent receiver, the received signal being subjected to one or more impairments in Amplifier Gain Control (AGC) mode, the one or more impairments including PDL; estimating an AGC gain effect of the AGC mode; compensating for the AGC gain effect in the received signal; determining the PDL from the compensated signal; and reporting the PDL.
A method of monitoring a polarization dependent loss (PDL) of a signal during transmission through an optical communication link, the method comprising:
A coherent receiver configured to monitor a polarization dependent loss (PDL) of a signal during transmission through an optical communication link, the coherent receiver comprising:
