摘要： In wavelength division multiplexing (WDM) systems, one optical multiplexing section (OMS) can support several channels. During a network reconfiguration, the number or channel index of the channels in the OMS may change, which may result in a change in gain for other channels in the OMS due to the channel loading dependant gain properties of many optical amplifiers. Equalization is therefore required in order to reduce power excursion for the channels in the OMS. Using a model for the channel loading dependent gain of optical amplifiers, equalization may be performed more quickly than using measurement-based equalization methods. The model predicts the change in gain for the channels in an OMS following network reconfiguration, and allows for an equalizer to quickly or pre-emptively adjust for the changes. This model may include an artificial neural network, which is trained using some of the possible channel loading conditions for the OMS.

摘要： The inclusion of a pilot tone as a modulation of an optical data signal reduces the optical signal to noise ratio (OSNR). Methods and apparatus for receiving an optical signal are provided that compensate for at least a portion of the pilot tone modulation to reduce the pilot tone induced OSNR penalty. An initial waveform is processed to generate a compensated waveform, the processing including dispersion compensation. An intensity waveform is calculated in accordance with the compensated waveform. The intensity waveform is processed to obtain a pilot tone frequency, a modulation depth, and a phase of the pilot tone. The compensated waveform is multiplied with a pilot tone compensation factor that is a function of the pilot tone frequency, the modulation depth, and the phase of the pilot tone to generate a modified compensated waveform. A symbol carried by the modified compensated waveform is determined.

摘要： Aspects of the present application provide an optical interconnecting network architecture. The architecture involves a central node coupled to multiple access nodes (ANs), in which the central node includes a pair of optical couplers used to combine optical signals received from the ANs and broadcast the combined optical signals to all destination ANs. A coherent detection receiver in each of the ANs receives the combined optical signals and selectively detects a wavelength carrying the optical signal assigned to that AN by tuning a local oscillator (LO) wavelength of the coherent detection receiver.

摘要： Systems and methods for performing wavelength conflict detection are provided. These are to detect situations in optical networks where two instances of the same wavelength channel have been added. Wavelength conflict detection is performed for each of a plurality of possible wavelength channels that could be present in an optical signal, each wavelength channel that is present modulated by a pilot tone signal with a respective pilot tone frequency, the pilot tone signal carrying M-ary pilot tone data, M=2n, n≥1, with a respective one of M different sequences being used to represent each of M possible data values over a data value period. Conflict detection for each wavelength channel involves performing correlation peak detection using each of the M different sequences to determine correlation peaks for each of the M different sequences, and, based on the determined correlation peaks, determining whether multiple instances of the wavelength channel are present in the optical signal.

摘要： An aspect of the disclosure provides methods and systems for encoding a data bit stream onto a pilot tone signal. Another aspect of the disclosure provides method and systems for pilot tone detection. In both, a coded pilot tone signal is encoded using a code sequence m1 for each bit value of 1 (b1) and a code sequence m0 for each bit value of 0 (b0) of a data bit stream including pilot tone data bit values of 1 (b1) and bit values of 0 (b0), with each code sequence having multiple coding bits in the duration of each bit. Pilot tone detection can further include decoding each code sequence of the coded pilot tone signal using a plurality of successive overlapping measurement windows. In some embodiments each measurement window is of the same duration, being of the duration of each code sequence, and detecting each code sequence comprises selecting one of the plurality of measurement windows to represent a complete code sequence.

摘要： The present applies to digital wavelength converters that convert, independently of the format in which optical data may be encoded, an input waveform at a first wavelength to an output waveform at a second wavelength. When operating in an environment where an input waveform has a pilot tone associated thereto, the method and system of the present disclosure allows for the removal of the pilot tone from the input waveform, and also allows for the addition of another pilot to the output waveform.
