Patent attributes
A telecommunications network component comprising: a processor configured to implement a method comprising: receiving an optical signal comprising at least one identification signal, the identification signal comprising a series of frequency portions that alternate in turn according to a frequency interval defined for each of the series of frequency portions, partitioning the identification signal by way of a plurality of windows, performing a Fast Fourier Transform (FFT) on each of the plurality of windows, determining which of the plurality of windows comprise a relative minimum number of frequency components, and detecting an optical channel based on results of the FFT performed on each of the plurality of windows that comprise the relative minimum number of frequency components.
