Simulative analysis of 32x40 DWDM systems for return to zero modulation schemes using variation in channel spacing

Abstract

The Dense Wavelength Division Multiplexing (DWDM) is an optical fiber transmission framework that utilizes firmly dispersed light frequencies and transmits many data at the same time. This gives a practical technique to expand the limit of the existing system. The goal of the existing Fiber multi-channel communication system is demonstrating the concept of DWDM communication system cover up more and more data to send and receive a whole long stretch communication framework. In this analysis, we using OptiSystem simulation software for 32 x 40 GB/s DWDM communication fiber length 50 km Single-Mode Fiber (SMF) at Different channel Spacing likewise 80GHz, 90GHz and 100Ghz in DWDM for bit rate 40 Gb/s. Dispersion can be completely compensated with the aid of using Dispersion compensating fiber as a compensator. In this paper, the general execution of 32 channel DWDM correspondence with 40 Gbps bit rates researched.
