Performance analysis of 80 channels hybrid optical time division dense multiplexing system with the support of different orthogonal modulation techniques

Abstract

High spectral transmission capacity signals are the prime requirement of today’s dense communication system to enhance the quality of different users services, which have been analyzed and resolved with the support of 80 channels hybrid optical time division dense multiplexing system with different orthogonal modulation techniques (return to zero (RZ), differential quadrature phase shift keying (DQPSK), non-return-to-zero (NRZ), polarization shift keying (PoISK), and differential phase shift keying (DPSK)). Further, evaluation has also been proceeded to receive the best rating results in terms of bit error rate (BER) and quality factor (38 dB to 20 dB) with attainable rating power amplification from Erbium-Doped fiber amplifier (EDFA). Furthermore, final examine has recommended that orthogonal DPSK modulation is the best choice to attain the data rate of 1.80 Tbps from the recommended system for 200 km optical communication with acceptable rating from 10^-24to 10^-10.
