摘要
The method involves measuring strength of optical signals delivered to commutation unit (4), and comparing the strength to a preset threshold to deliver instructions that represent the result of the comparison. The optical strength of the signals coming from commutation unit output is controlled based on received instruction, such that the strength of the signals at the input of the demultiplexer is maintained constant. Independent claims are also included for the following: (a) a device to control power of an optical signal for a transparent commutation node in an optical communication network (b) a transparent commutation node for an optical communication network.
