Abstract
A method and apparatus is proposed for use in a communication system in which an optical communications path including a plurality of optical spans, each of the optical spans contributing nonlinear distortions to an optical signal passing there-through includes, providing a dispersion pre-compensation to the optical signal in the optical communications path, such that the limiting nonlinear effect that produces signal distortions for long-haul transmission is suppressed, prior to transmission through a plurality of optical spans, and providing a dispersion post-compensation to the optical signal in the optical communications path after transmission through the plurality of optical spans.
