Optical amplifier repeater |
摘要 |
An optical amplifier repeater is provided having a first optical amplifier that amplifies a main signal light and supervisory signal light transmitted on an up optical-fiber transmission line and a second optical amplifier that amplifies the main signal light and supervisory signal light transmitted on a down optical-fiber transmission line. Further, a transfer unit that is provided transfers part of the supervisory signal light transmitted on the up optical-fiber transmission line onto the down optical-fiber transmission line and transfers part of the supervisory signal light transmitted on the down optical-fiber transmission line onto the up optical-fiber transmission line. The transfer unit has an optical amplifier output side transfer unit that transfers supervisory signal light reflected by a first light-reflecting device inserted to the output side of the first optical amplifier to the output side of the second optical amplifier, and transfers the supervisory signal light reflected by a second light-reflecting device inserted to the output side of the second optical amplifier to the output side of the first optical amplifier.
