Method and apparatus for determining whether the configuration of an optical transmission interface should be adjusted, method and apparatus for configuring an optical transmission interface, and information storage medium
For determining whether a configuration of an optical transmission interface of a first device has to be adjusted for transmitting optical signals to a second device via an optical band-pass filter, the second device having an optical reception interface configured to enable 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: monitoring an evolution of a difference level between codewords received by the second device via said optical signals and corresponding codewords transmitted by the first device; and determining whether the configuration of the optical transmission interface of the first device has to be adjusted, on the basis of said monitoring.
