Optical communication transmission systems improvement based on chromatic and polarization Mode dispersion compensation simulation management

•Dispersion compensation technique is the most important issue in the optical communication system to overcome dispersion challenge.•The optimum transmission performance enhancement of optical communication system has been realized.•The gain is 126 dB that is recognized within the proposed dispersion compensation model. Dispersion compensation technique is the most important issue in the optical communication system to overcome dispersion challenges. The current study focuses on a proposed compensation simulation model to handle not only chromatic dispersion (CD) but also polarization mode dispersion (PMD) simultaneously. The present compensation model is designed to analyze and simulate dispersion compensation technique which is based on deploying both fiber Bragg grating and emulator together till 250 km long of optical fiber. Signal to noise ratio (SNR), optical signal to noise ratio (OSNR), gain (G), noise figure (NF) and degree of polarization (DOP) are parameters that simulation depends on.
