Power line communication is abbreviated as PLC technology, its basic principle refers to utilizing the low-voltage grid to transmit multimedia signals, such as data, voice, picture, etc. at a high speed, that is to say, low-voltage power line acts as information carrier loaded with signal, modem functions as receiver separate signals from power line, then the signals are conveyed to the equipments, such as computers or telephones, etc. , in order to realize information transmission.
PLC technology takes on remarkable characteristics such as no connection up, wide coverage, convenient joint, high quality, fast transmission speed, and being steady, suitable for the residential quarters, hotels, offices, safeguard systems etc. , especially suitable for broadband reconstruction in the already built up architectures, thereby it is hailed as one of the most competitive technologies for the last kilometer solution by the insiders.
PLC equipments consist of router, repeater and modem.
Low-voltage power line modem GD51X1-MODEM is a access equipment for terminal computer linking to PLC broadband. It demodulates signals from power line, and sends signals to users' terminal network equipments directly.
GD51X1-MODEM has five indicator lamps (POWER, LINK, ACT, COL, LINK/ACT) ; a power interface; a RJ _ 45 interface; a USB interface. a USB and a RJ _ 45 selection switches.
