Power line communication system using hybrid-fiber coaxial and communication device used in the system
Abstract:
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.
Abstract(Chinese):

一种利用混合光纤同轴电缆（HFC）的电力线通信（PLC）系统中使用的通信设备，其包括PLC光网络单元，PLC中继桥式放大器，PLC分配放大器和PLC耦合设备。 在这种情况下，PLC光网络单元不需要在每个用户位置通过电缆调制解调器和PLC调制解调器对以太网信号进行PLC协议转换，并且能够在每个用户位置和使用PLC的通信终端之间进行PLC通信 以太网信号，通过经由光纤从光发射机接收光信号，将光信号转换为与预定PLC协议相对应的PLC以太网信号，并通过同轴传送PLC以太网信号至少一个用户位置 电缆。
