摘要： A system and method for method of managing a network. Each of a plurality of servers includes an element management system (EMS) function for managing network elements within the network and a network management system (NMS) function for managing ones of the plurality of servers running the EMS function. An NMS function is activated on one of the servers when the plurality of servers shares a one network domain. When the network domain is divided into multiple domains, e.g. by a network failure, an NMS function is activated on at least one other one of the plurality of servers whereby each of the multiple network domains has at least one associated active NMS function.

摘要： An optical transmission system may include a combination of higher gain repeaters and lower gain repeaters, arranged to manage gain tilt. The higher gain repeaters and lower gain repeaters may be arranged to allow net gain to vary (e.g., above and below zero) within a predetermined acceptable net gain excursion. In one embodiment, the higher gain repeaters have a nominal gain value higher than a nominal span loss value and the lower gain repeaters have a nominal gain value lower than the nominal span loss value.

摘要： A receiver for a differentially phase shift keying formatted optical signal, such as an RZ-DPSK formatted optical signal. Dither control loops are provided for controlling path length in a demodulator and/or for controlling the center wavelength of an optical band pass filter. A feedback loop is provided for controlling the gain of a pre-amplifier, and a method of protecting against optical transients by disabling a pre-amplifier is also provided. A preset delay may be provided to compensate for the differential delay in paths associated with the demodulator arms. When the signal is an RZ-DPSK modulated signal, a clock for retiming data from the optical signal may be derived from a signal on the data path.

摘要： A system and method for spectral loading unutilized channels of a partially loaded WDM system may be used to suppress spectral hole burning (SHB). Dummy tones may be loaded at different loading wavelengths within the band of system wavelengths such that the loading wavelengths are associated with a subset of unutilized channels in the WDM system. The loading wavelengths may be selected and spaced based on a distortion in the gain spectrum of the partially loaded WDM system such that the dummy tones alter the distortion to provide a desired gain spectrum.
