In this paper, the types of modulation that support high-capacity transmission in 5G networks and beyond are discussed. Different types of digital modulation (DP-PSK , DP-QAM) and their impact on the quality of received bits are discussed. Appropriate methods are suggested for transmitting the signal for distances up to 200 km and with an acceptable number of bit errors per unit time (BER) with acceptable values of acceptable values of signal power to the noise power, (SNR) ratio . with totally transmission bit rate approximately 6.4Tb/s . So , We describe the architecture of passive optical networks with coherent wavelength division multiplexing (PONs) Which helps to support fifth generation networks and beyond.

Optical transmission impairments are most critical reason to reduce both capacity and achievable transmission distance in optical communication system. Advanced modulation formats are important keys to reduce optical transmission impairments in digital signal processing (DSP) based coherent wavelength division multiplexed (WDM) system. These formats are more robust to non-linearity of optical fiber and results in increasing both spectral efficiency and bandwidth. Coherent detection technique increases sensitivity of receiver up to 30 dB in comparison of direct detection. Simulink seems to be the best cost-effective platform for analyzing mathematical modeling of optical coherent system. In this paper, mathematical model has been developed to analyze the optical transmission impairments by employing the advanced polarization multiplexed QPSK modulation in DSP based WDM coherent system. The simulation results have shown bit error rate (BER) improvement up to 10−6 and enhanced transmission distance to 150 km. These values have seen to be in close proximity with experimental results. The developed mathematical model seems to be more useful for extending the existing WDM optical system for longer distances with acceptable BER.
