TDMA passive optical network OLT system for broadcast service

The present invention provides a TDMA (Time Division Multiple Address) PON (Passive Optical Network) OLT (Optical Line Terminal) system for broadcast service, including packet processor, header information (IP address of packet header, MAC (multiple access control) address of Ethernet frame etc.) for receiving data by using outer nodes or ONT (Optical Network terminal) to determine information according to frame type (unicast, multicast and broadcast frames) and output port of switch, and the second data are generated by adding the information onto the header of the frame; a switch, copying the second data predetermination times according to transmission way and transferring the second data to corresponding output port according to identification code; M TDMA PON MAC processors, removing the identification code added onto the second data and transforming the second into TDMA PON frame; and M optical transceivers transforming TDMA PON frame into light signal and transferring the light signal to ONT.
