An optical amplifier repeater using two-stage semiconductor laser amplifiers with automatic power control (APC) system was inplemented for the first time. The APC system was realized by the direct monitoring of the amplified signal power. The assessment of the optical amplifier repeater confirmed the usefulness of the APC syster.
