Performance Analysis M-PAPM WDM-PON System with ASE-Powered Stealth Channels for Steganography Applications

Wavelength Division Multiplexing (WDM) boosts a physical medium's carrying capacity. Light frequencies within a frequency range are assigned to incoming optical communications (wavelengths or lambdas). Dense Wavelength Division Multiplexing (DWDM) has lately acquired favor as a low-cost method of increasing the transmission capacity of existing fibre cable connections. DWDM was formerly solely used in baseband digital applications, especially in terrestrial long-distance networks and, in certain cases, metropolitan and commercial networks. The performance of DWDM components and frequency-stabilized lasers has lately skyrocketed, while their costs have plummeted. As a result, a variety of novel optical network configurations have become commercially viable. Different types of DWDM systems, such as point-to-point, tree, and ring networks, are developed based on application needs. Each of these systems needs an own set of parts. Because it provides greater management and protection measures, the ring configuration is preferred above all others. A multichannel high-speed DWDM ring with 16 channels and a channel spacing of 0.4 nm was developed in this work. Each channel has a 10 Gbps data rate. The performance optimization of the DWDM ring using various modulation techniques was discovered on the simulated ring. As a comparison, the MPAPM modulation format was employed. Different modulation formats' BER and Eye diagrams were compared and analyzed. MPAPM outperformed CRZ, NRZ, RZ, and DPSK, according to research. The Electronic Dispersion Compensation (EDC) iii technology, which includes Decision Feedback Equalizers (DFE) and Feed Forward Equalizers (FFE) equalizers, can extend the transmission distance even more.
