The present article demonstrated an 8-channel c and l band WDM system using radio over fiber. The radio over fiber is a boon for the modern era of 5G and beyond communication. Many communication applications use only the C band, which is highly congested. The proposed method makes use of both the C (1530-1565 nm) and L (1565-1625 nm) bands. C and L bands provide low fibre attenuation and are thus preferred for Radio over Fiber communication. The presented scheme has a data rate of 8x10 Gbit/s. The laser pumping is comparatively low at the transmitter, only -5 dBm. Optisystem 19 was used to simulate this system. This system is evaluated using parameters such as BER, SNR, OSNR, quality factor, and eye diagram. The design works best up to a fiber length of 60 km. This approach makes use of SMF fiber with a wavelength of 1550 nm. The article reports Q factor and BER of 7.70, 6.74, 6.99, 7.91, 6.31, 5.42, 5.98, 6.08, and 6.62e-15, 7.24e-12, 1.23e-12, 1.22e-15, 1.38e-10, 2.94e-08, 1.08e-09, 5.93e-10 at 60 km of optical fiber
