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 ( 12 ) for comparing input optical power measurements to a selected first threshold and generating instructions representative of the comparison result, secondly, a measuring device ( 10 A) for delivering measurements representative of the input optical power of the optical signals at one output at least of the switch ( 4 ), and thirdly, a processor between the switch ( 4 ) and the multiplexer ( 6 ) of the node and which control the optical power of the signals coming from the switch ( 4 ) as a function of the instructions they receive, so that the optical power of the signals at the input of the multiplexer ( 6 ) is maintained substantially constant.
