Abstract
An optical communication system for transmitting telephone voice data to a subscriber terminal using an optical line is disclosed. The system includes an OLT (Optical Line Terminal) multiplexing the telephone voice data together with the broadcasting data and communication data, converting the optical signals transferred upward into electric signals, demultiplexing and converting the uplink telephone voice data into analog telephone voice signals to transfer the converted analog telephone voice signals to a PSTN; a plurality of ONTs (Optical Network Terminals) for converting the optical signals transferred from the OLT into electric signals, demultiplexing and converting the demultiplexed downlink telephone voice data into analog signals to transfer the converted analog signals to subscribers' telephones; and an optical branching filter for branching the signals from the OLT to the plurality of ONTs, combining, and transferring the signals from the plurality of ONTs to the OLT.
