Abstract:
1. A termination apparatus contained in a termination end of a WDM/SCM (Wavelength Division Multiplexing/Sub-Carrier Multiplexing) PON (Passive Optical Network) to connect the WDM/SCM PON with either a subscriber or an Ethernet service network, comprising: 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 over a plurality of SCM channels; and a MAC (Media Access Control)-bridge module for performing a multiplexing/demultiplexing operation based on a MAC address upon receipt of frames communicated between the Ethernet service network and the WDM/SCM PON, correcting an SFD (Start Frame Delimiter) position of the frames to provide a delay time difference of more than 0 between adjacent frames, distributing Ethernet frames to individual SCM channels, and interfacing the distributed Ethernet frames with the WDM/SCM physical layer module.
