Abstract
A device (D) is dedicated to controlling the power of optical signals in a transparent switching node of an optical communication network that switches bands of wavelengths. The device includes, firstly, a controller () for comparing input optical power measurements to a selected first threshold and generating instructions representative of the comparison result, secondly, a measuring device (A) for delivering measurements representative of the input optical power of the optical signals at one output at least of the switch (), and thirdly, a processor between the switch () and the multiplexer () of the node and which control the optical power of the signals coming from the switch () as a function of the instructions they receive, so that the optical power of the signals at the input of the multiplexer () is maintained substantially constant.
