Optical network termination apparatus in wdm/scm pon

The present invention relates to a wavelength-division-multiplexed and multiplexed sub-carriers based on multi-channel WDM optical network to support the integration efficiently / SCM-based passive optical network of the terminal device as the service compatible with the Ethernet network. The configuration of the present invention is provided in the wavelength division multiplexing (WDM) and the sub-carrier multiplexing (SCM) based on the end of a passive optical network according to the termination device to connect to the passive optical network and the subscribers, or an Ethernet service network, an Ethernet service network or It is associated with a subscriber, Ethernet matching module for performing Ethernet Interface function; WDM / SCM-based passive optical network is physically connected to the WDM to perform transmission and reception of optical signals to the Passive Optical Network / SCM physical layer module; And a transmission and reception frame, and the multiplexing / demultiplexing on the basis of the MAC address, to reconstruct a frame of the preamble by each channel, comprises MAC- bridge modyulreul to matching by SCM channel of the WDM / SCM physical layer.
