        abstract = {The study of the coherent optical fibre transmission network for next generation optical networks is presented using a C-band spectral analysis to determine the power of the adjacent channels. Using the intra-link optical network, the scheme of polarisation multiplexed-quadrature phase shift keying (PM-QPSK) is employed to compare probabilistic and conventional deterministic systems. The proposed design is validated using wavelength division multiplexing (WDM) radio over fibre (RoF) system. Further, to obtain more insight about the system characteristic, PM-16QAM (Polarisation multiplexed-quadrature amplitude modulation) and PM-QPSK system margins are analysed. It is observed that the optical launch power range of 4 dB has a maximum inaccuracy of 0.4 decibels. In addition, the coherent WDM optical system up to 6 dB dispersed link are analysed across 1000 discrete instantiations of PM-QPSK and PM-16QAM schemes using polarisation dependent loss (PDL) measurement. Over a 6 dB range of launch optical powers, the system gives less than 1 dB of signal-to-noise ratio (SNR) loss.},
