Multiplexers work to optimize light signals transmitted through the fiber cables. Sometimes multiplexers are referred to as ‘muxers’, these devices collect data so that the info can be transmitted across a single fiber. The process occurs before the data travels towards its end-point. With the help of wavelength division multiplexing, several data streams can run on a single fiber. This process is possible because a wavelength of light doesn’t directly disrupt the light pulses around it. A light source will emit pulses when one is entered into the input field. If no light pulses are emitted, then a zero has been entered
- Trunk: The trunk acts as a transmission line, trunks are the fiber cables that transmit the signal. An optical networking can be made up of either multiple trunks, or one trunk.
- Router: A router is positioned inside a communication network, acting as a path for signal transmission.
Amplifiers are used to support transmission over longer distances, amplifiers are useful to reduce degradation of the signal. The amplifier receives the signal and then multiples the signal to increase the strength. There are several different types of optical amplifiers, and all of them rely on different transmission techniques. Here some types include Optical amplifiers Fiber Raman, semiconductor amplifiers, Brillouin, and Rare earth doped fiber amplifiers.
