Two technologies with great impact have been wireless and fiber optic communications. Using radio frequency (RF) signals, radio has provided us with military radars, avionics, cellular and satellite communications; Our world is safer and more interesting thanks to all the benefits provided by the wireless advances. We no longer need to be 'homebased' for an expected call or to pick up a podcast; our banking, fitness, transportation, communications and home safety routines can be programmed and controlled from our mobiles.
With glass filaments coating like your spine, fiber optic networks provide the ability to carry a lot of data thanks to its huge bandwidth. In terrestrial telecommunications and in the distribution of cable television (CATV), fiber optic networks have taken over from copper wire, conducting telephone conversations and specialized content more efficiently and with greater reliability. They allow our varied entertainment selections and allow our devices to be part of the Internet.
The link between these two technologies is RF Over Fiber (RFOF), also known as Radio Over Fiber (ROF).
ROF is an analog transmission that uses RF signals to modulate light that is transmitted through a fiber optic cable. At the receiving end, the RF energy is recovered. The optical link provides a low-bandwidth, high-bandwidth communications link for transporting RF energy at optical frequencies, and then the RF signal is recovered for use at the point of loading.
