The development of 5G communication networks intends to transmit data across great distances with better capacity to meet user requirements. Several academics and communication firms sought to solve the difficulty of managing a dense communication channel network. This thesis proposes and designs an 80-channel Dense Wavelength Division Multiplexing (DWDM) Radio over Fiber (RoF) system employing the NRZ coding scheme and 0 dBm laser source input power. The suggested system may reduce chromatic dispersion by utilizing the strong symmetrical compensation mechanism. The sample channels were 1,4,8,12,16, ......., and 80, and the transmission distance spanned from 60 km to 300 km. The proposed system is further analysed for multiple coding schemes of RZ and NRZ with varied input power values ranging from -5 dBm to 5 dBm to determine its optimal dependability. The mean QF and BER were 9.577 dBm and 2.34E-14, respectively, for 300 km transmission. RZ performs better for short distances (less than 100 km), whereas NRZ performs better for long distances up to 300 km. NRZ with a ± 5 dBm input power fluctuation also increased the BER by roughly E-4 and had an average effect variation of about ± 0.3 dBm in the QF values. However, raising the input power to 5 dBm lowered the mean total BER by approximately E-2, showing that power may lessen the effect of errored bits conveyed. However, RZ with ±5 dBm input power fluctuation lowered input power to -5 dBm and reduced QF by 1 dB. The suggested system's performance improves by 3 dBm by increasing the input power to 5 dBm. confirming the input power-QF connection. Increased input power may produce long-range transmission nonlinearity. BER values ranged from E10 to E-20. Additionally, altering input power by ± 5 dBm has a modest effect on QF outcomes, with mean QF ranging by roughly ± 0.1 dBm. RZ coding has a variance effect of less than 0.1 dBm. These findings demonstrate the proposed system's reliability for 2 Tbps transmission up to 300 km.
