    摘要： In an apparatus and method for troubleshooting a transmission system comprising optical line amplifiers (OA), optical reflections can be detected irrespective if a data signal is present or absent. Each OA is equipped with a self-stimulation signal detection unit for generating a low frequency local code unique to the transmission system and dithering the outgoing signal in a controlled manner with the local code. Each OA attempts to detect its local code in the incoming signal by comparing the energy of the transmitted and received dithers. The presence of the local code in the incoming signal initiates alarms which unequivocally identify the faulted OA. Each OA selects its local code out of a bank of local codes, according to a priority scheme and re-selects its local code in case of conflicts.

    摘要： The invention is directed to a failure detection system and method for detecting malfunction of an optical amplifier module with one or multiple transmission channels. The failure detection system comprises a unit for measuring a performance parameter of the module; a unit for providing an expected performance parameter; and a comparator unit for receiving the performance parameter and the expected performance parameter and producing an error signal when the performance parameter substantially departs from the expected performance parameter. The system also includes a display/alarm unit for receiving the error signal and accordingly signaling failure of the module. The performance parameter is an output value of the module; a correspondence between an output value and an input value for a transmission channel; a figure of merit (FOM.sup.t=t); a set of gains (g) for all transmission channels; and the dynamic range of the amplifier module.

    摘要： An optical modulator may include a first interferometer arm and a second interferometer arm, a first microring resonator disposed along the first interferometer arm, the first microring resonator having a first resonant wavelength, and the first resonant wavelength having a first difference from a carrier wavelength. The optical modulator may include a second microring resonator disposed along the second interferometer arm, the second microring resonator having a second resonant wavelength, and the second resonant wavelength having a second difference from the carrier wavelength. The difference between the first and second resonant wavelengths and the carrier wavelength defines a first and second microring resonator detuning, respectively. The second microring resonator detuning and the first microring resonator detuning have opposite signs. The optical modulator may include a first modulation line electrically connected to the first microring resonator, and a second modulation line electrically connected to the second microring resonator.

    摘要： A method for preventing nonlinear interference in an optical communication system. The method may include selecting an optical signal of a first optical channel. The method may include determining an estimate of inter-channel nonlinear interference to the optical signal of the first optical channel. The inter-channel nonlinear interference may be generated by one or more optical signals transmitted over a second optical channel in the optical communication system. The method may include determining one or more linear filters based on the estimate of the inter-channel nonlinear interference. The method may include pre-distorting an optical signal for transmission over the second optical channel using the one or more linear filters. The pre-distorted optical signal may be configured for reducing the inter-channel nonlinear interference to the first optical signal of the first optical channel. The method may include transmitting the pre-distorted optical signal over the second optical channel through an optical transmission medium.
