摘要： An intelligence-defined optical tunnel network system includes multiple Optical Switch Interconnect Sub-systems (OSIS), in which a first OSIS is configured to transmit a first lateral transmission optical signal via a first line to a second OSIS, and transmit a second lateral transmission optical signal via a second line to the second OSIS. The second OSIS includes a failover sub-module and a micro-control unit. The failover sub-module is configured to output one of the first and the second lateral transmission optical signal based on a selective signal. The micro-control unit is configured to output the selective signal to the failover sub-module to control the failover sub-module output the second lateral transmission optical signal if a signal intensity of the first lateral transmission optical signal is lower than a threshold value.

摘要： A device includes a threshold setting unit that sets a threshold for an input optical power monitor to detect the input optical power to the optical transmission line of an active system; a threshold deciding unit that decides whether the input optical power to the optical transmission line of the active system detected by the input optical power monitor is not greater than the threshold set by the threshold setting unit or not; and an attenuation controller that carries out, when the threshold deciding unit decides that the input optical power is not greater than the threshold, system switching by controlling first variable optical attenuators so as to gradually reduce attenuation of the signal light rays input from the optical transmission line of one backup system, and to gradually increase attenuation of the signal light rays input from the optical transmission line of the active system.

摘要： To allow only a route with the failure to be automatically switched from a currently used route to a redundant route when a failure occurs in one of the routes in a transmission system including a first route and a second route each of which has a redundant route, a route switching device 1 according to the present invention includes a first selection means 10 for outputting a first main signal, a second selection means 20 for outputting a first switching command signal, a first transmission means 30 for transmitting an inputted signal to a counterpart device, a second transmission means 40, a first receiving means 50, a second receiving means 60, a first monitor means 70 for outputting an abnormality notification if an abnormality in a second main signal is detected, and outputting a first switching command notification if second information is included in a second switching command signal, a second monitor means 80, and a third selection means 90 for obtaining a second main signal from a selected receiving means. The first selection means 10 and the second selection means 20 switch a selection destination when a first switching command notification has been inputted. The second selection means 20 outputs a switching command signal including second information when an abnormality notification has been inputted. The third selection means switches a selection source when an abnormality notification has been inputted.

摘要： 10-Gbps client signals (1a to 1c) which are processed by a 10-Gbps transponder (3a), a 40-Gbps transponder (3b), and a 100-Gbps transponder (3c), respectively, are branched by optical couplers (2a to 2c) into an M:N switch (40). The M:N switch (40) selects a client signal to be made redundant from the branched client signals (1a to 1c) and outputs the selected client signal to a redundancy 100-Gbps transponder (50) having 10-Gbps-based client interfaces.
