摘要： To provide a technology of preventing an optical signal from being mistakenly recognized as an optical noise even when a surge occurs. A control device of a node that transfers signal light monitors inputted light, determines, when power of the inputted light reaches a saturation level of a monitor unit as a result of monitoring, that the inputted light is signal light, further determines based on a spectral line shape of the inputted light, when the power thereof does not reach the saturation level, whether the inputted light is the signal light or ASE light; and stops a transfer of the ASE light if determined to be the ASE light.

摘要： An optical node apparatus according to the present invention amplifies a WDM signal light input to an input port, and thereafter, branches the amplified WDM signal light by an optical branching coupler to send the branched lights to first and second optical paths, and selects the light propagated through the first optical path by an optical switch to amplify the selected light by a post-amplifier, thereby outputting the amplified light from an output port, when the optical node apparatus is operated as an optical amplification repeating node. When the operational state is upgraded to an optical add/drop multiplexing node, an OADM section is connected between a set of connecting ports on the second optical path, and the adjustment of the OADM section is performed utilizing the WDM signal light branched by the optical branching coupler, and thereafter, the switching of the optical switch is performed to select the light on the second optical path side. As a result, since the switching the operational state from the optical amplification repeating node to the OADM node can be performed in a short time, it becomes possible to provide the continued communication service at the low initial installation cost.

摘要： An optical transmission network includes a first dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value and searched out from within a maximum dispersion route having a maximum dispersion value from among routes of non-regeneration intervals within which a dispersion value before dispersion compensation does not satisfy an upper limit of a dispersion tolerance, and a second dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value searched out from within a maximum dispersion route having a maximum dispersion value from among the routes when a dispersion compensator is successively arranged until a route of a non-regeneration interval within which a dispersion value of a certain channel does not satisfy the dispersion tolerance does not remain any more based on the dispersion value after the dispersion compensation with respect to the searched out maximum dispersion span. The dispersion compensation amounts of the first and second dispersion compensators are such that, when the dispersion compensation amount of the maximum dispersion span in which the first and second dispersion compensators are arranged is successively increased, the span has a residual dispersion value equal to or higher than a fixed range and the maximum dispersion route which relates to the spans has a residual dispersion value which satisfies the dispersion tolerance or the span has a residual dispersion value which is within the fixed range.

摘要： The present invention aims at providing an optical switch changeover controlling method, an optical node device and an optical switch system, capable of avoiding an interruption in an optical output power when changing over an optical path making use of a spatial optical switch arranged with a plurality of optical switch elements. To this end, the optical switch changeover controlling method according to the present invention enables an uninterrupted changeover of an optical path by conducting a reconnection of the optical path after establishing a state where the optical path before the changeover and the optical path after the changeover are simultaneously set concerning the spatial optical switch within the optical node device, when conducting a changeover of the optical path so as to transmit a client optical signal having been transmitted through a working ray path to a protective ray path such as in a case that a fault occurs in the working ray path.

摘要： A protection switch comprising a demultiplexer, optical selector, a multiplexer, and a monitor circuit is provided on the input side and the output side of an optical XC node. The demultiplexer demultiplexes the wavelength-multiplexed optical signals of a 0-system and a 1-system, and transmits these optical signals to the optical selectors which are provided for the respective wavelengths. The optical selectors are controlled by the monitor circuit, and switch the optical signal of one system to that of the other system when a fault occurs. The optical signals of the respective wavelengths outputted from the optical selectors are multiplexed by a multiplexer to be transmitted. The demultiplexer and the multiplexer can be differently arranged depending on the configuration of a transmission line or the optical XC node. Further, a multi-wavelength selection filter such as an acousto-optical filter or the like can be used as a protection switch.

摘要： A bossless computer program architecture in which each program module is hierarchically equal is used to develop complicated software applications. Each program module is associated with a parameter file. The characteristics and operation of the program modules are determined by their associated parameter files. These modules communicate by writing statements to the parameter files associated with other modules. Once written, the origin of these statements is ignored. Thus, there is no need to “return” to the modules which originate the statements. Further, the statements are executed by the modules without regard to their origins. This new architecture does not require the preservation of linkage information because there is no need for the program modules to return information or control to other modules. Various applications of this architecture to windows-based environment and multimedia applications are disclosed.

摘要： A method for driving the motor of multiple phase, where the number of windings in the coil of each phase can be changed, either in a first mode where all the windings in the coil of each phase are used or a second mode where the number of windings used is smaller than that of the first mode. The driving method includes a source voltage detector for supplying the driving method with a source voltage, a temperature detector for detecting an ambient temperature about the motor, and a controller for switching the action of the driving method to run the motor in either the first mode or the second mode in response to a result of the detection released from the source voltage detector or the temperature detector. Accordingly, the revolution of the motor can be maintained constant hence providing a degree of energy saving.
