摘要： In an optical repeating system including an optical transmitter and optical amplifying repeaters, the optical transmitter specifies one optical amplifying repeater, and transmits to the optical amplifying repeater a supervisory command to supervise internal circuits of the optical amplifying repeater and a control command to control amplification factors of optical amplifiers of the optical amplifying repeater as a first sub-signal. Receiving the supervisory command via an optical transmission line, the optical amplifying repeater transmits a supervisory signal indicating a supervisory result corresponding to the supervisory command to optical receivers via optical transmission lines as a second sub-signal. Receiving the control command via the optical transmission line, the optical amplifying repeater is controlled to change amplification factors of the optical amplifiers in response to the control command.

摘要： A supervisory system and supervisory method of an optical amplifier repeater are proposed that can implement operation supervision taking account of the characteristics of individual supervisory targets of the optical amplifier repeater, thereby achieving higher reliability. The supervisory system includes an optical transmitter for transmitting an optical signal including an operation command to notify of a state of a supervisory target; an optical amplifier repeater that transmits a response optical signal including a response code obtained by measuring the supervisory target in response to the operation command; an optical receiver for receiving the response optical signal via an optical fiber and an information processing unit for converting the response code into a numerical form by using a predetermined expression that links the response code with measured information obtained by measuring in advance the supervisory target with an external measuring device during operation of the optical amplifier repeater in response to the operation command.

摘要： To provide an apparatus for measuring chromatic dispersion when modulating frequency of a variable wavelength light source is different from modulating frequency of a fixed wavelength light source for reference. This apparatus is provided with a variable wavelength light phase comparator 24 for obtaining a phase difference &phgr;x-&phgr;x′ between a variable wavelength light component and a signal having the first modulating frequency fmx, a fixed wavelength light phase comparator 25 for obtaining a phase difference between a phase difference &phgr;0-&phgr;0′ between a fixed wavelength light component and an electrical signal having the second modulating frequency fm0, a phase difference converter 26 for converting the phase difference &phgr;0-&phgr;0′ calculated by the fixed wavelength light phase comparator 25 into &phgr;ex, which corresponds to the first modulating frequency fmx, and a true phase difference calculator 27 for measuring a true phase difference &phgr; between the phase difference &phgr;x-&phgr;x′ calculated by the variable wavelength light phase comparator 24, and the converted result &phgr;ex of phase difference converter 26, and obtains the true phase difference &phgr; from which an affect of contraction/extension of a DUT 30 is removed when the first modulating frequency fmx and the second modulating frequency fm0 are different, thereby measuring wave dispersion.
