Performance Analysis and Simulation of Dense Wavelength Division Multiplexing System in the Presence of Optical Amplifiers

Abstract

In this research work different aspects of optical amplifiers in terms of channel spacing, newlinepower compensation, gain, noise-figure and fiber losses have been analyzed for dense optical newlinecommunication system. Analysis of 200 channels of dense wavelength division multiplexing newline(DWDM) system with the effect of data rate of 14 Gbps for acquiring the flat gain for the newlinechannel wavelength range from 1520 nm to 1640 nm have done with optical amplifiers. newlineAnalysis of dense communication system has also explored with the amplification of the newlinesignal power of erbium-ytterbium co-doped optical amplifier (EYBCDOWA) and RAMAN newlineamplifier (RA) for the optical transmission length of 120 km to minimize the effect of newlinecrosstalk and bit error rate (BER). Overall analysis of recommended proposed DWDM newlinesystem is capable to deliver the flat gain of 19.5 dB with minimum variation of .95 dB to newlinemaintain the acceptable dense optical communication for long distance communication. High newlinespectral transmission capacity signals are the prime requirement of today s dense newlinecommunication system to enhance the quality of different users services, which has analyzed newlineand resolved with the support of 80 channels hybrid optical time division dense multiplexing newlinesystem with different orthogonal modulation techniques (return to zero (RZ), differential newlinequadrature phase shift keying (DQPSK), non-return-to-zero (NRZ), polarization shift keying newline(PoISK), and differential phase shift keying (DPSK) newline
