Abstract:
1. An optical networking device for re-amplifying, re-shaping, and re-timing an optical signal, as well as providing distortion compensation and performance monitoring of the optical signal, comprising: an all-optical regenerator device for two or more of re-amplifying, re-shaping, and re-timing the optical signal; a distortion compensator device for compensating for distortion associated with the optical signal; and a quality-of-signal monitoring device for measuring the quality of the optical signal, wherein the quality of the optical signal is measured subsequent to demultiplexing and after the all-optical regenerator device and the distortion compensator device and before subsequent multiplexing and amplification of the optical signal, and wherein the quality-of-signal monitoring device is operable for performing fault isolation on a per channel basis; wherein the quality-of-signal monitoring device provides feedback to the distortion compensator device subsequent to demultiplexing and then the feedback-modified optical signal is provided to the all-optical regenerator device; and wherein the distortion compensator device compensates for one or more of chromatic dispersion, polarization mode dispersion, bandwidth limiting, and self-phase modulation associated with the optical signal.
