Optical performance monitoring (OPM) and optical network management (ONM) are essential in building a reliable and high quality of service system as the optical transmission system continues to evolve towards higher data rates, increased wavelength density and longer transmission distances. Traditional OPM primarily focused on achieving the desired functionality and prove to be insufficient for next...
We proposed a novel algorithm for carrier phase estimation with differential demodulation, phase coupling between both polarizations and non-redundant error correction. The algorithm is demonstrated on measured 111 Gb/s polarization-multiplexed QPSK with 10times10.7 Gb/s OOK neighbours.
