Abstract: PURPOSE: A wavelength multicasting method in the multiple-ring network, a multiple-ring network apparatus, and a node of the multiple-ring network are provided to implement the wavelength multicasting in the multiple-ring network node by separating a signal by using a simple separation/coupling device. CONSTITUTION: Each node (101) of each ring network system comprises a channel extracting/passing module (102), a multiplexer (103), an optical coupler (104), and a band cutoff filter (105). An optical amplifier (106) is equipped between the nodes. Among each node, the node, which is used in the signal exchange with other ring networks, is coupled by extracting and inserting an optical signal by using the optical separator and optical coupler. Each of a single ring network is able to extract the optical signal, which came from other ring network, and the signal, which is inserted from the single ring network. The extracted signal is outputted by separating into the band, channel, or the whole signal. The band cutoff filter prevents the interference with the optical channel, which is sent from own node, by separating own signal after transmitting to the adjacent node.

Abstract: An apparatus for switching an OTH(Optical Transport Hierarchy) signal frame in an ATCA platform is provided to switch a large switching capacity and provide a multicast and ADM(Add and Drop Multiplexer) function to provide the same function as that of an existing SDH switch. A processor unit(200) is connected with a fabric interface unit of an ATCA(Advanced Telecom Computing Architecture) platform and controls ODU data received through an input port. An ethernet controller controls ethernet communication to the fabric interface unit. A cross point switch unit(220) is connected with a line card, an input/output unit of the ATCA platform, to cross-switch a 2.5Gbps signal between node slots. A chip set driver signal generating and controlling unit(230) is implemented as a circuit configuration for a control signal required for each function part for implementing an OTH unit switch, an address decoding logic for a bus with the processor unit, and a circuit of a processor bus converter for a processor connection unit of a switch element. A back board connection unit(240) uses a double star structure based on a switch slot including the fabric interface unit, and connects a management channel for managing each line card slot to a base channel to interface the 2.5Gbps signal. A duplex function part(250) interchangeably mounts/dismounts two switch units in the ATCA platform, performs switching on the switch units due to a failure, and generates a control signal to allow each line unit to select one of two received signals.
