摘要： A communication/broadcast multiplexer and demultiplexer for multiplexing and demultiplexing communication and broadcast signals using a specific transmission standard in an optical network system that integrates broadcast and communication services using a channel selection technique. The multiplexer comprises a broadcast data input unit, a communication data input unit, and a synchronous Ethernet framer. The broadcast data input unit receives broadcast data switched on a subscriber basis through a broadcast switch in an optical line terminal (OLT) in the system, and transfers it as a synchronous data frame to the synchronous Ethernet framer. The communication data input unit receives communication data on a subscriber basis through an Ethernet switch in the OLT and transfers it as an asynchronous data frame to the synchronous Ethernet framer. The synchronous Ethernet framer converts both the received synchronous and asynchronous data frames into a TDM synchronous Ethernet frame, and outputs the TDM synchronous Ethernet frame.
