In terms of technology, 5G uses radio waves for sending and receiving data while Fiber optic communication uses light to transmit data through fiber optic cables. Whereas 5G can have downlink speed up to the scale of 20 Gbps and 10 Gbps uplink, practical speed measured on Fiber cables is 100 Gbps. Related- 5G vs 4G.
