MULTICHANNEL OPTICAL CROSS-PHASE MODULATION COMPENSATOR

摘要

PROBLEM TO BE SOLVED: To provide a multichannel optical cross-phase modulation compensator.;SOLUTION: A method and a system for multichannel optical XPM modulation may include a DCM for improving the performance of a forward feedback control loop in an optical path in an optical network. As in the ROADM node, various spectrum overlap methods may be used together with a multi-channel WDM optical signal by using the XPM compensator in parallel. The polarization diversity may be supported for XPM compensation including the DCM.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2018,JPO&INPIT
