摘要:
A termination device for use in a WDM-SCM PON system can effectively support a multi-channel integration function of a WDM/SCM PON system. The termination device contained in a termination end of a WDM/SCM (Wavelength Division Multiplexing/Sub-Carrier Multiplexing) PON (Passive Optical Network) to connect the PON with either a subscriber or an Ethernet service network includes: an Ethernet interface module connected to the Ethernet service network or the subscriber to perform an Ethernet interface function; a WDM/SCM physical layer module physically connected to the WDM/SCM PON to transmit/receive optical signals to/from the WDM/SCM PON; and a MAC (Media Access Control)-bridge module for performing a multiplexing/demultiplexing operation based on a MAC address upon receipt of transmission/reception frames, and reconstructing preambles of the frames while being classified according to channels so that individual Ethernet frames are matching-processed while being classified according to SCM channels of the WDM/SCM physical layer module.
