摘要

Differential Quadrature Phase Shift Keying (DQPSK) is considered as an acceptable modulation technique for long-haul high speed communication owing to its ability to diminish the Polarization Mode Dispersion (PMD), non-linear effects and has constant envelope over the communication. The assessment includes Carrier Suppressed Return to Zero (CSRZ) modulation format. The combination of CSRZ and DQPSK techniques would result in a high bit rate with better Bit Error Rate (BER) in Wavelength Division Multiplexing - Passive Optical Network (WDM-PON) setup. The Radio Frequency (RF) signal is obtained finally for wireless service which can be assessed. . The optical communication system is expanded by comprising Polarization Multiplexing (PM) which improves the user scope and the spectral efficiency. The goal is to experimentally analyze the performances of CSRZ-DQPSK modulated non-coherent receiver for wire and RoF (Radio over Fiber) system for wireless service. Also, equal amount of power is provided for both the services. The PMD is reduced both the services. The Proposed system can provide flexible, cost-effective and high bandwidth utilization with reduced BER.
