Multi-wavelength optical batch amplification apparatus

摘要

The invention provides a multi-wavelength optical batch amplification apparatus wherein, upon batch amplification of a multi-wavelength input optical signal, the powers of optical signals on the input and output sides of an optical amplifier are monitored totally or individually to control the powers of optical signals of the output optical signal of the optical amplifier so that they may be fixed equally. The apparatus includes an entire input light detection section (7) for monitoring the power of the entire input optical signals on the input side of the optical amplifier (4), an individual output light detection section (8) for monitoring the powers of the output optical signals on the output side of the optical amplifier (4), an optical amplifier output adjustment section (9) for adjusting the output of the optical amplifier (4), and a control section (10) for controlling the optical amplifier output adjustment section (9) based on results of detection by the entire input light detection section (7) and the individual output light detection section (8) so that the powers of the output optical signals on the output side of the optical amplifier (4) may be fixed equally.
