Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Radio over fiber is a wireless communication technology where radio signals sent by equipment to base stations modulate a light, transmitting optical data. The data moves through fiber to access telecommunications hubs. Returning signals coming in the other direction go through the base station, which emits radio waves for equipment to pick up. This method provides a number of advantages over cable-based wireless communications where users plug a router into a phone line or coaxial cable to access the Internet and other networking services.

Global Radio over fiber (RoF) market was valued at 353.59 Million US$ in 2018 and is projected to reach 608.51 Million US$ by 2024, at a CAGR of 9.47% during the forecast period. APAC accounted for the largest share of the RF-over-fiber market in 2017, followed by North America and Europe.
