摘要： Provided is an apparatus for implementing an electro-optical cable distribution network in which a coaxial cable is replaced with an optical cable in order to provide a service integrating broadcast data and communication data by solving a frequency constraint problem in a cable television (CATV) network employing a conventional hybrid-fiber coaxial (HFC) network architecture. The apparatus includes an optical network unit (ONU) which converts a downstream signal received from a system operator (SO) into an optical signal and transmits the optical signal to an optical cable; and an optical cable modem which receives the optical downstream signal from the ONU and converts the received signal into an electrical signal. In addition, the ONU and the optical cable modem control signal quality of an optical path.
