Inter-channel nonlinearities in hybrid OOK and coherent PDM-QPSK transmission systems with dispersion management
19 July 2010
We show that in dispersion-managed systems with co-propagating 10-Gb/s OOK and coherent PDM-QPSK channels, it is the inter-channel XPM from the 10-Gb/s OOK channels that significantly degrades the performance of the coherent PDM-QPSK channels.
