RF Transmitters, Receivers, Transceivers
The process of sending and receiving radio signals through wireless networks involves two devices, the transmitter, and the receiver. The receiver picks up the waves with its antenna or aerial and turns the electric signal back into the sound where it can be heard.
Transceivers are wavelength-specific lasers that convert electrical data signals from data switches into optical signals. These signals can then be transmitted over the optical fiber. Each data stream is converted to a signal with a unique wavelength, meaning that it is effectively a unique light color.
