摘要： PROBLEM TO BE SOLVED: To increase the number of optical transmission apparatuses connectable to an optical hub node device. SOLUTION: To an azimuth unit 10 comprising N pieces of ports to each of which another azimuth unit 10 is freely removably connected, N or less pieces of azimuth units 10 selected from among N+1 or more pieces of azimuth units 10 are connected, so that an optical hub node device includes N+1 or more pieces of azimuth units 10. As a result, in comparison with the case where N+1 pieces of azimuth units 10 are connected completely in a mesh shape, the number of azimuth units 10 is increased. Therefore, the number (degree) of optical transmission apparatuses connectable to the optical hub node device is also increased. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical wavelength multiplexed transmission apparatus, capable of automatically determining the transmittability of a path, in a wavelength multiplexed optical communication network.
SOLUTION: Each network device holds as a database parameters relating to the size of a factor of signal degradation of the device, and relays the parameters according to a path through which a signal passes. When each network device receives a relayed parameter, it accumulates the parameter of the device to the received parameter value, and transmits the result to the network device at the next stage. The network device on the terminating side of the path estimates the size of the degradation of the signals in the entire path by using the received parameter, thereby determining the reachability as to whether or not a signal can be transmitted through the path with quality higher than the predetermined quality.

摘要： PROBLEM TO BE SOLVED: To provide a WDM(wavelength division multiplex) terminal that can contain a plurality of client signals from remote places at a low cost and to provide a WDM network. SOLUTION: The WDM terminal is provided with a multiplexer means that applies wavelength multiplex processing to at least either of other client wave signal or a plurality of other client wave signals subjected to wavelength multiplex processing onto a plurality of client signals subjected to wavelength multiplex processing and transmits the result and the WDM terminal can contain the client signals subjected to wavelength multiplex processing at a low cost because the terminal can apply wavelength multiplex processing to the client signals subjected to wavelength multiplex processing sent from a short distance WDM terminal at a remote place without the need for demultiplexing by each wave onto other client signals.
