    摘要: Provided are a method of and apparatus for processing a virtual local area network (VLAN) tag frame. The apparatus includes a filtering data base (FDB) for storing a VLAN tag frame which is created by a gigabit passive optical network (GPON) master; an uplink processing unit for removing by referring to the FDB a VLAN tag from the VLAN tag frame which is received from the GPON master, and transmitting a data frame to an Ethernet switch; and a downlink processing unit for inserting by looking up the FDB a VLAN tag into the data frame which is received from the Ethernet switch, and then transmitting the data frame to the GPON master. According to the present invention, port identification (ID) information that is lost in a GPON master may be provided to a switch above the GPON master by using a VLAN tag frame processing technology.

    摘要: Provided is an apparatus for matching Gigabit Ethernet (GbE) signals to an Optical Transport Hierarchy (OTH). The apparatus real-time records a source address and input port information of GbE Ethernet frames in a memory, compares a destination address of the Ethernet frame which is a payload of a GFP frame with memory table information, searches an output port location of the GbE, and interreceives GbE frames and Generic Frame Procedure (GFP) frames by multiplexing/demultiplexing.

    摘要: Provided is a multi-mode open-loop type clock extraction apparatus. In the apparatus, a power divider block divides an input data signal into two data signals. A first band-pass filter block and a second band-pass filter block extract a first clock frequency component or a second clock frequency component contained in the data signal output from the power divider. A first amplifier block and a second amplifier block amplify the first clock frequency component and the second clock frequency component respectively. Accordingly, it is possible to extract the respective clock signals corresponding to N data rates from the N data signals with various data rates using a single clock extraction apparatus.
