Optical Link Design of 5G Triple-Band Radio over Fiber Using Wavelength Division Multiplexing Technique

The need for communication networks with high speed and capacity continues to increase along with the development of information and communication technology. 5G technology applied to Radio over Fiber accompanied by Wavelength Division Multiplexing can meet these needs. Fronthaul schemes were designed with radio frequencies of 0.7, 2.6 and 26 GHz. Simulations in the upstream and downstream schemes showed that channel 1 and channel 2 in the upstream scheme had reached the target with a BER value of less than 1e009 and a Q Factor of more than 6. In the downstream scheme, no channel reaches the target.
