摘要

This paper proposes a novel hybrid model of a soliton-based Dense Wavelength Division Multiplexing (DWDM) system with 8 channels delivering an aggregate capacity of 320 Gbps, integrated with optical-layer encryption and Multiple Input Multiple Output–Orthogonal Frequency Division Multiplexing (MIMO-OFDM) for wire and wireless communication. The design leverages the nonlinear stability of soliton pulses to mitigate dispersion-induced impairments in long-haul transmission, while embedding physical-layer encryption to ensure secure data delivery. The originality of this work lies in the joint optimization of soliton dynamics, encryption mechanisms, and MIMO-OFDM modulation, enabling both spectral efficiency and confidentiality with minimal performance overhead. System performance is assessed using OptiSystem and MATLAB simulations over distances from 60 to 180 km, with the help of Dispersion Compensating Fiber (DCF) and Fiber Bragg Grating (FBG) with variations in channel scalability and input power. Results indicate a high Q-factor (~ 42.74), near-zero Bit Error Rate (BER), and stable operation at a 12 dB Signal-to-Noise Ratio (SNR), even under challenging long-haul conditions. The integration of encryption and MIMO-OFDM introduces negligible latency or resource overhead while supporting high-speed, secure transmission compatible with emerging 5G, 6G, and Wi-Fi standards. These results demonstrate the potential of soliton-based DWDM combined with MIMO-OFDM as a viable solution for next-generation optical backbone networks requiring efficiency, resilience, and strong physical-layer security.
