摘要： A communication equipment which is utilized in a power line communication (PLC) system utilizing a hybrid fiber coax (HFC) which includes a PLC optical network unit, a PLC trunk bridge amplifier, a PLC distribution amplifier, and a PLC coupling device. In this instance, the PLC optical network unit does not require a PLC protocol conversion of an Ethernet signal by a cable modem and a PLC modem in each subscriber location, and enables a PLC communication between the each subscriber location and a communication terminal utilizing a PLC Ethernet signal as is, by receiving an optical signal from an optical transmitter via an optical fiber, converting the optical signal into the PLC Ethernet signal corresponding to a predetermined PLC protocol, and transmitting the PLC Ethernet signal to at least one subscriber location via a coaxial cable.
