Method and apparatus for increasing a transmission performance of a hybrid wavelength division multiplexing system

摘要

A hybrid wavelength division multiplexing system wherein one or more amplitude modulated signals generated by optical amplitude modulators are co-propagated with one or more phase modulated signals generated by optical phase modulators, wherein a drive voltage of said optical amplitude modulator is adapted to reduce an extinction ratio of the amplitude modulated signal to minimize a cross-phase modulation impact on the co-propagating phase modulated signal.
