High-Power Optical Fiber Transmission Technologies for Radio-Over-Fiber Networks

The development of optical fiber transmission technologies has led to the emergence of various types of optical fibers have been introduced. In addition, the increase in the transmission capacity of optical fiber communications and the emergence of new applications have gained significant attention in high-power transmission technologies. Particularly, for beyond 5G/6G networks that are based on radio-over-fiber, which transmits wireless radio frequency signals along fiber links, power-over-fiber and high-power signal transmissions are important for the availability and simplification of remote antenna units in mobile communications to improve the scalability. This paper introduces various types of optical fibers and describes representative high-power transmission technologies that use specialized optical fibers.
