Electronic Pre-Compensation of Intra-Channel Nonlinearity in a 10Gb/s Optical Transmission System

Abstract

We introduce several new algorithms for compensating intra channel nonlinearities in lightwave systems through electronic predistortion. These were optimized and modeled assuming realistic conditions at Nortel and were found to be insensitive to normal environmental and design fluctuations in commercial systems. We also present an upper bound on system performance that agrees well with measured results.
