Chromatic Dispersion Compensation in 80Gbps Ultra High Bit Rate Long-Haul Transmission with Travelling Wave Semiconductor Optical Amplifier

Abstract

This paper proposes a novel dispersion compensation method using Optical Phase Conjugation (OPC) method with travelling wave Semiconductor Optical Amplifier (SOA) at a data rate of 80Gbps. This method can replace the large optical filters in the existing method using Fiber Bragg Grating (FBG). The performances are measured in terms of critical parameters like OSNR, FWM conversion efficiency, output optical power and output electrical power. Results show that our method can improve the optical power about 18dB from existing method. This proposed method can increases the OSNR about 38dB and RF power about 15dB from the existing method. The conversion efficiency can also be improved about 3dB from the existing method.
