METHOD AND OPTICAL COMMUNICATION SYSTEM FOR TRANSMITTING A DATA SIGNAL USING ELECTRICAL PRECOMPENSATION AND SINGLE SIDEBAND MODULATION

摘要

From the data signal (DS) is a predistorted modulation signal (MDS) by an electrical precompensator (EDC) derived comprising at least properties of a phase shifting filter that substantially mitigates the influence of dispersion (DC) and nonlinear effects imparted to the to the optical communication signal (OSSB-RZ) by the optical communication system. The predistorted modulation signal (MDS) is used to modulate an optical carrier signal (CW) to generate a corresponding predistorted optical single sideband communication signal (OSSB-RZ; OSSB-AMI-RZ) for transmission over the transmission link (FI).
