Comparative Efficacy Estimation of OIDMA System using Gaussian and Soliton Pulses for Long Haul Communication

Abstract

This article contains the comparative analysis of optical Soliton pulses verses Gaussian pulses, used in convolutionally coded OIDMA system. Earlier a lot of work has been done on OIDMA system using LASER source at input with Gaussian pulses and the output detection is done by APD. An optical Soliton pulse which is intense and narrow in shape has the property to propagate larger distance in non linear optical medium without changing its shape and velocity. Such optical Soliton pulse property is utilized in OIDMA system and BER of system is analyzed. The complete OIDMA system is programmed on MATLAB and at the electrical to optical conversion section the LASER diode with 1mW input power and Gaussian shape pulses, and optical Soliton pulses are connected separately for comparative analysis purpose.
