This research examines the design and performance of a 32-channel high-speed optical data transmission system at 40 Gbps, using Non-Return-to-Zero (NRZ) and Return-to-Zero (RZ) modulation methods under a Dense Wavelength Division Multiplexing (DWDM) setup. NRZ modulation is investigated for spectral efficiency and performance at shorter transmission distances, and RZ modulation is considered for resistance to dispersion and nonlinear degradations and is best suited for long-haul communications. Simulation with OptiSystem software compares system performance based on Q-factor, Bit Error Rate (BER), and Eye Diagrams with respect to different channel spacings and transmission lengths. The results prove that while NRZ provides more efficiency at shorter distance links, RZ maintains better signal quality at larger distances. This research gives significant insight into optimizing modulation methods for future advanced optical communication systems and its application in telecommunications, data centers, and high-performance computing networks.

摘要

This research examines the design and performance of a 32-channel high-speed optical data transmission system at 40 Gbps, using Non-Return-to-Zero (NRZ) and Return-to-Zero (RZ) modulation methods under a Dense Wavelength Division Multiplexing (DWDM) setup. NRZ modulation is investigated for spectral efficiency and performance at shorter transmission distances, and RZ modulation is considered for resistance to dispersion and nonlinear degradations and is best suited for long-haul communications. Simulation with OptiSystem software compares system performance based on Q-factor, Bit Error Rate (BER), and Eye Diagrams with respect to different channel spacings and transmission lengths. The results prove that while NRZ provides more efficiency at shorter distance links, RZ maintains better signal quality at larger distances. This research gives significant insight into optimizing modulation methods for future advanced optical communication systems and its application in telecommunications, data centers, and high-performance computing networks.
