ABSTRACT:
A device (D2) is dedicated to controlling degradation parameters associated with signals on channels with different wavelengths, possibly arranged in bands of channels, and transmitted by transmission lines (Lj) connecting nodes (Ni) of a transparent optical communication network. The device includes processing means (PM2) adapted, in the event of transmission of signals of at least two channels or bands of channels by at least one transmission line (Lj), to measure for each of said channels or each of said bands of channels, firstly, the value of a parameter representative of the degradation of the signals on the corresponding line (Lj) and, secondly, taking account of said measured values, a power profile to be imposed on the signals so that they have predetermined degradation parameter values.
