Power line communication (PLC), also called Mains Communication, Power Line Telecoms (PLT), Powerband or Power Line Networking (PLN), is a term describing several different systems for using power distribution wires for simultaneous distribution of data. The carrier can communicate voice and data by superimposing an analog signal over the standard 50 or 60 Hz alternating current (AC). It includes Broadband over Power Lines (BPL) with data rates sometimes above 1 Mbit/s and Narrowband over Power Lines with much lower data rates. Traditionally electrical utilities used low-speed power-line carrier circuits for control of substations, voice communication, and protection of high-voltage transmission lines. High-speed data transmission has been developed using the lower voltage transmission lines used for power distribution. fiber loss,fiber power,propagation delay,optical loss,optical, length,optical power,fiber test,fiber Test Fiber Optic Cable with Your Digital Multimeter. A short-range form of power-line carrier is used for home automation and intercoms.

Types of PLC technology

Indoors/Short Range

the PLC equipment can use the household electrical power wiring as a transmission medium. This is a technique used in home automation for remote control of lighting and appliances without installation of additional control wiring. The HomePlug system is an example of this technology. The X10 home automation system uses power line communication at the zero crossing voltage point in the AC wave. Greenlee 560XL Fiber Optic Power Meter | ToolUpcom.
