Abstract:
A dispersion compensated optical communication system, comprising:a multi-channel system of lasers; a plurality of spans of fiber operatively connected at an input end to said laser system for receiving signals therefrom and having an output end, each of said plurality of spans of fiber having a transmitter end and a receiver end in series; a plurality of optical amplifiers, each disposed at an input to one of said spans of fiber; a pre-transmission dispersion compensator applied to said input end of said plurality of spans of fiber; a post-transmission dispersion compensator applied to said output end of said plurality of spans of fiber; the ratio of dispersion compensation provided by said pre-transmission dispersion compensator and said post-transmission dispersion compensator being pre-selected so as to provide a predetermined distribution of dispersion compensation in the system.
