System and method for recovery of clock to optical communications consistent with polarization diversity

摘要

System and method for recovery of clock to optical communications consistent with polarization diversity.The present invention which applies the optical communication systems of high rates, with multiplexing in polarization, with recovery of the clock by means of digital signal processing in the receiver proposes a system and method for recovery of clock for communications coerent With the diversity of bias by estimating the error of timing immune to rotation polarization signal.The system consists of a block of estimation and correction of rotation of polarization, operating in closed loop. The method of polarization properties of symmetry using signals multiplexed polarization around the main states of polarization.
