Abstract: Provided are methods of transmitting and receiving a multicast or broadcast frame in an optical line terminal (OLT) and an optical network unit (ONU) for a wavelength division multiplexing (WDM)-passive optical network (PON), a WDM-PON system, and an OLT for a WDM-PON. The method of transmitting a multicast or broadcast frame in an OLT for a WDM-PON includes converting and splitting a multicast or broadcast frame input using a single wavelength into a plurality of wavelengths, combining the split wavelengths, and outputting the multicast or broadcast frame. In this way, a multicast or broadcast frame can be transmitted and received, thereby providing a single copy broadcast (SCB) function in a WDM-PON.

Abstract: An Ethernet device having multiple lanes and a method of operating the lanes are provided. In one general aspect, it is possible to allocate a dummy block to each of one or more lanes such that the lanes do not selectively participate in communications. In addition, on a receiving side, the dummy block can be removed from among the genuine data blocks to enable data to be decoded. In this case, an Ethernet device on a transmission side and an Ethernet device on a receiving side can exchange information of a lane to which the dummy block is allocated by use of a lane status message, and the lane status message may be based on a link fault message specified by Ethernet standards.

Abstract: Provided are a local area network (LAN) emulation method and an information storage medium. The LAN emulation method provides a LAN emulation function in an arrayed-waveguide grating (AWG)-based wavelength division multiplexing (WDM)-passive optical network (PON) using a mode bit and a logical link identifier (LLID).
