Abstract:
Embodiments of this disclosure provide an apparatus and method for monitoring a polarization dependent loss, a receiver and a communication system. The apparatus for monitoring a polarization dependent loss includes: a first processing unit configured to process received optical signals, to obtain a first correlation matrix of noise signals in the received optical signals and a second correlation matrix of second signals or other signals in the received optical signals other than first signals or spectral feature signals having predetermined spectral features; a matrix subtraction unit configured to subtract the second correlation matrix by the first correlation matrix, to obtain a third matrix; and a calculating unit configured to perform singular value decomposition on the third matrix, and calculate a polarization dependent loss according to a result of the singular value decomposition. According to the embodiments of this disclosure, the polarization dependent loss may be calculated more accurately.

Claim (Index 8):
A communication system, comprising a transmitter and a receiver; wherein,\n the transmitter is configured to transmit optical signals containing payloads and signals with known frequencies to the receiver, frequencies of the signals with known frequencies being different in two polarization states of the optical signals; and the receiver is the receiver as described in  claim 7 .
