Abstract:
1. A system for optical signal dispersion and parameter monitoring comprising: a tunable filter configured to receive an optical signal comprising a plurality of channels and configured to filter a portion of one channel from the plurality of channels, wherein, during dispersion monitoring, the portion includes a test signal; a polarization beam splitter (PBS) coupled to the tunable filter and configured to receive the portion from the tunable filter and split the portion into a first polarization beam and a second polarization beam; a first photodetector coupled to the PBS and configured to receive the first polarization beam from the PBS and convert the first polarization beam into a first electrical signal; a second photodetector coupled to the PBS and configured to receive the second polarization beam from the PBS and convert the second polarization beam into a second electrical signal; and a control unit coupled to the first photodetector and the second photodetector and configured to:
