Hi,
Radio over fiber means a technology in which light is modulated by a radio signal and transmitted over an optical fiber link to facilitate wireless access, such as 5G and WiFi simultaneous from the same antenna.
i.e. radio signals are carried over fiber-optic cable.
Radio over Fiber technology (RoF), an integration
of wireless and fiber optic networks, is an essential technology
for the provision of untethered access to broadband wireless
communications in a range of applications including last mile
solutions, extension of existing radio coverage and capacity,
and backhaul.The traditional link between the radio base station (RBS) and
the antenna has previously been a copper coaxial cable. To use
an optical fiber cable instead, makes both design of new sites,
as well as the physical deployment of the hardware, much
easier.
Thanks,
