Title: Investigation of 40Gbps Dispersion Compensated DWDM System Incorporating Different Optical Pulses
Abstract: The focus of this paper is to report a detailed investigation of dispersion compensated DWDM system with equal channel spacing incorporating pre-, post-and symmetrical-dispersion compensation techniques (DCF) with different optical pulses.The proposed high speed DWDM system is demonstrated with dispersive standard single-mode fiber (SSMF), which is compensated with proportionate length of DCF fiber under different DCF compensation schemes.Further, a performance comparison of pre-, post-and symmetrical-DCF schemes is reported by computing Q-parameter, and required optical power at receiver sensitivity at varied values of laser linewidth to underscore the best possible performance.A connection among the attributes like laser line-width, different optical pulses and different DCF schemes is reported at 10Gbps.
