Method for determining equalization parameters in an optical transmission via an optical band-pass filter

摘要

For determining equalization parameters for performing equalization for optical signals transmitted by a first device to a second device via an optical band-pass filter, the second device being configured for receiving optical signals output by said optical band-pass filter and transmitted by the first device on a carrier wavelength when said carrier wavelength is comprised in the passband of the optical band-pass filter, said carrier wavelength and/or said passband of the optical band-pass filter being a priori unknown, a monitoring device performs: determining information representative of a level of detuning between the carrier wavelength of the optical signals and the nominal wavelength of the optical band-pass filter; and determining said equalization parameters, on the basis of said determined information representative of the level of detuning between the carrier wavelength of the optical signals and the nominal wavelength of the optical band-pass filter.
