Efficient Echo-Cancellation Algorithms for Full Duplex Coherent Optical Systems

Not Accessible

Your library or personal account may give you access

Abstract

A digital echo-cancellation method to identify and mitigate reflection impairments in full duplex coherent optical links is proposed. More-than 6 dB improvements in echo power tolerance are experimentally verified in a 32-GBd full-duplex DP-QPSK link.
