Linear and Non-Linear Compensation in High Capacity Optical Communication Systems

The objective of this work is to present and analyze different digital signal processing methods oriented to compensate and mitigate the effects of chromatic dispersion (CD) and nonlinearities affecting the performance of high capacity optical communication systems. The approach was to perform the equalization using the Digital Backward Propagation (DBP) and Volterra filters methods. Offline processing routines were developed. Simulations were performed for different optical communications links scenarios with frequencies up to 100 Gbps and lengths between 800 y 2400 km. The methods were compared according to their performance and computational complexity.
