摘要
The present invention relates to an optical system with an optical amplifier having at least one input and output, a control circuit for controlling the output power of the amplifier with the aid of an output process demand signal (PD) from a control means. The control circuit comprises control means, a detector block and a means for tapping off light from an input or an output of the optical amplifier to the detector block. According to the invention, at least one check signal (A) is disposed to be sent in at least one check signal channel which passes through the optical amplifier. The detector block is configured to measure the amplitude of the control signal(s).
