Abstract
A method () of non-linear propagation impairment equalization, the method comprising the steps of: a. receiving () communications traffic carried by an optical communications signal transmitted over an optical communications link; b. generating () a time dependent filter representation of a nonlinear time-variant impulse response of the inverse of the optical communications link; and c. applying () the time dependent filter representation to the received communications traffic to form non-linear propagation impairment equalized communications traffic. An optical communications link nonlinear propagation impairment equalizer and optical communications signal receiver apparatus are also provided.
