摘要： A link connectivity verification message to recognize a physical link connection state is transmitted from the WDM to the PXC on a C-plane. The PXC transmits a link connectivity verification ACK message including information representing a physical link connection state, and the WDM transmits a cross-connect instruction message to cross-connect a transmission side and a reception side of a port (port 1) of the PXC. Probe light transmitted from the port (port a) of the WDM is turned back by a cross-connect of the port (port 1) of the PXC. The WDM receives the probe light to verify a link connectivity.

A control means which includes a route and wavelength selecting functional part 32, transmits a request band information and a wavelength information based on a requested band information, link information of a network, and band limitation information with respect to each filter wavelength of the optical filter 38. A multi-rate functional part 36 sends a bit rate varying request to set a band to be requested to the network side according to the requested band information. A wavelength varying functional part 37 sends a wavelength varying request to set a wavelength of the optical signal according to the wavelength information. The optical filter 38 includes a bit rate (band) dependent wavelength multiplexing and demultiplexing functional part 39.

摘要： An optical fiber transmission line for realizing satisfactory long haul transmission characteristics using two kinds of optical fibers. The optical fiber transmission line includes a plurality of local dispersion compensating spans, wide dispersion compensating spans disposed at predetermined intervals, and optical repeating amplifiers to connect each span. The local dispersion compensating span includes a first optical fiber with positive dispersion having an effective core area of 130 &mgr;m2 or more and a second optical fiber with a negative dispersion value of −50 ps/nm/km or less to transmit the light output from the first optical fiber. The wide dispersion compensating span consists of a third optical fiber having the same configuration and composition with the first optical fiber.

摘要： Between photonic cross connects (PXCs) 3 and 4, an in-use system path passing through transmission apparatus (WDMs) 5 and 7 are set, and a backup system passing through transmission apparatus (WDMs) 6 and 8 is set. The WDMs 3 and 4 link to the PXCs 5 and 7 and release masking therebetween when the in-use system path is set, and set masking therebetween when the in-use system path is deleted. The WDMs 5 and 7 included in the in-use system path transmit an alarm to a monitoring system when an input light is turned off, and the WDMs 6 and 8 included in the backup system path do not transmit an unintended alarm to the monitoring system even when the input light is turned off.
