SUBSCRIBER OPTICAL DISTRIBUTOR APPLIED TO BROADCAST COMMUNICATION INTEGRATED SERVICE, ESPECIALLY IN RELATION TO SUPPLYING SEPARATED BROADCAST AND COMMUNICATION SIGNALS TO SUBSCRIBERS IN FTTH(FIBER TO THE HOME) OPTICAL TRANSMISSION NETWORK

摘要

PURPOSE: A subscriber optical distributor applied to a broadcast communication integrated service is provided to separate broadcast and communication signals when supplying a broadcast communication integrated service to subscribers, and to transmit the separated signals to a broadcast interface and a communication interface, respectively, thereby increasing applications. CONSTITUTION: An optical transceiver(41) receives TDM broadcast/communication optical signals from an ONU to perform an optical/electric conversion, and transmits an uplink signal of a user to the ONU by performing an electric/optical conversion. A broadcast/communication signal distributor(42) receives the broadcast/communication signals, and separates the broadcast signal from the communication signal when transmitting the signals. A broadcast interface(43) receives the broadcast signal to output the signal. A communication interface(44) receives the communication signal to output the signal, and receives the uplink signal to transmit the signal to the optical transceiver(41).
