Abstract In recent years, with the swift development of the internet industry, people urgently necessitate extra capacity and speedy network systems. Under this circumstance, optical fibers are becoming the most favourable delivering media as it has a major important role in the information business, with their huge bandwidth and excellent transmission performance. Dispersion compensation is the main important attribute required in an optical fiber communication system because the presence of dispersion leads to pulse spreading that causes the output signal pulses to overlap. For a long-haul transmission system, an 8x1 Wavelength Division Multiplexing Multi Input Multi Output (WDM MIMO) channel with a novel dispersion compensation system has been designed. Various dispersion compensation techniques are explored in this work, including dispersion-compensating fibers, fiber Bragg grating, Ideal compensation Bragg grating, and opti-grating, with a 2.5 Gbit/s data rate for each channel. With a power of 20 dBm, the proposed model is simulated with 32768 samples. The length of an optical fibre can range from 5 to 100 kilometres. Throughout the simulation, the operation frequency is 193.1 THz. The software opti-system-17.0 was used to design and implement the system. The 8-channel device was used to simulate and calculate metrics such as Q-factor, Bit Error Rate (BER), and Signal to Noise Ratio (SNR). The proposed model enhances performance in terms of BER and quality factor at the receiver end of systems.
