SYSTEM AND METHOD FOR MONITORING POWER IMBALANCE INDUCED BY POLARIZATION-DEPENDENT LOSS

摘要

PROBLEM TO BE SOLVED: To provide a systems and method for monitoring a dual-polarization signal.;SOLUTION: The system and method includes extracting a portion of the dual-polarization signal, which includes multiple supervisory signals each associated with a polarization component of a main data signal, measuring a power level of the first and second supervisory signals, and determining a power imbalance between the polarization components of the main data signal on the basis at least of the power level.;COPYRIGHT: (C)2015,JPO&INPIT
