摘要： PROBLEM TO BE SOLVED: To provide a system enabling relaying by an optical network for setting a wavelength path between two optical burst switching networks.
SOLUTION: The system contains first and second devices. The first device generates an optical burst signal from transmission data, determines whether the wavelength path is maintained based on the time interval between the optical burst signal and the next signal, belonging to the same destination or the same communication, and generates the control packet of the optical burst signal including the determined result. The second device has a function of controlling the setting of a wavelength path to a network setting the wavelength path and maintains or cancels the set wavelength path, according to the determined result included in the control packet, when the wavelength path set to the network is used for transferring the received control packet and the optical burst signal.

摘要： PROBLEM TO BE SOLVED: To provide a multi-ring optical network system in which an optical signal to be transmitted over ring-configured optical networks can be transmitted while maintaining high quality and further, management operation of wavelength is facilitated. SOLUTION: Optical networks 1, 2 are configured by connecting nodes 1-1 to 1-5, 2-1 to 2-5 including WXC devices each constituted of a WSS in a ring shape. A node 4 is disposed in the middle of a transmission line 3 connecting the optical networks 1, 2 with each other. The node 4 has a signal quality management/enhancement function and compensates for quality deterioration of a transmitted optical signal. The node 4 also has a wavelength conversion function thereby also enabling the wavelength of the transmitted optical signal to be converted into a wavelength which can be used to a destination node. In place of disposing the node 4 or in addition to the node 4, the nodes 1-1, 2-1 can have the signal quality management/enhancement function. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a wavelength path setting method that calculates an OSNR index value accurately reflecting quality of a transmission path onto all routes selectable on end-to-end basis in a photonic network so as to be capable of setting a wavelength path to a route with optimum transmission quality.
SOLUTION: A link quality management function section 21 of an optical node manages an OSNR index value calculated on the basis of OSNRs of transmission paths among optical nodes. A route calculation function section 25 determines an optimum route on the basis of a total OSNR index value of each route from its own optical node to an end point optical node. This determination uses a maximum OSNR index value by each request band for wavelength path setting managed by a path quality management function section 23. A signaling function section 24 transmits path setting request information to the route calculation function section 25 and transmits a signaling message to an adjacent optical node to set a wavelength path to the optimum route determined by the route calculation function section 25.

摘要： PROBLEM TO BE SOLVED: To attain quick and efficient path switching by eliminating an excess procedure in the case of switching an active system path to a standby system path. SOLUTION: An optical network is provided with optical cross-connect apparatuses (PXCs) 3, 4 and transmission apparatuses (WDMs) 5 to 8. If a fault occurs in an active system path passing the WDM 5 and the WDM 6, the active system path is switched to the standby system path passing the WDM 7 and the WDM 8. The WDM 5 has a WDM notification protection time in which time required from the sending of an active system path deletion signal up to the sending of an active system path monitoring end signal can be minimized. When a fault of the active system path in the PXC 4 direction occurs, the active system path deletion signal from the PXC 3 is received by the PXC 4 and light in the PXC 3 direction is interrupted. Even when the light interruption is detected, the WDM 5 does not send a state notification signal to the PXC 3 within the notification protection time. Similarly, the WDM 6 also has the WDM notification protection time. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a link system of PXC and WDM which is capable of cutting and dividing troubles occurring between PXC-WDM, and operating an optical network with high reliability and high efficiency, in an optical network where working paths and standby paths are set up. SOLUTION: A current path passing through transmission units (WDMs) 5 and 7 is set up between optical cross-connection units (PXC) 3-4, and a standby path passing through transmission units 6 and 8 is set up. When the current path is set up, WDMs 5 and 7 cancel the mask processing between them in coordination with PXCs 5 and 7; and when the current path is canceled between WDMs 5 and 7, mask processing is set up between them. WDMs 5 and 7, included in the current path, appropriately sends out an alarm properly to a monitoring system, when input light is blocked; and WDMs 6 and 8 included in the standby path will not send out an unintended alarm to the monitoring system, even if the input light is blocked.

摘要： PROBLEM TO BE SOLVED: To improve transmission characteristic of WDM transmission. SOLUTION: An optical transmitting device 10 performs wavelength multiplexing of signal lights having wavelengths of λ1-λn and outputs them to an optical transmission line 12. Optical powers of the respective signal lights having the wavelengths of λ1-λn are identical, or the shorter the wavelength becomes, the smaller the power is. One transit span of the optical transmission line 12 is equipped with optical fibers 20, 22 and an optical amplifier 24. A gain equalizing device 26 is arranged every plural transit spans. The optical amplifier 24 in the transit span amplifies the signal lights in such a manner that the signal light power of the short wavelength side becomes smaller than that of the long wavelength side. The gain equalizing device 26 makes the optical powers of the respective signal lights equal.
