1. be used to analyze the circuit structure of the safe shutdown optical amplifier (V) that has Unit the 1st (E1) of the optical signalling (LW) of feed-in optical waveguide (L),It is characterized in that:

  • One the 2nd unit (E2) is set, with the spontaneous emission of amplification (ASE) of measurement feed-in optical waveguide (L),An identifying unit (ES) is set, the detected measured value (SR) that amplifies the optical signalling (LW) of spontaneous emission (ASE) of having eliminated is flowed to this identifying unit.
