Optical amplification apparatus, optical transmission system, and optical amplification method

Abstract

An optical amplification apparatus, an optical transmission system, and an optical amplification method that make it possible to suppress deterioration in signal light quality are provided. An optical amplification apparatus is an optical amplification apparatus connected between a first multi-core fiber and a second multi-core fiber, and includes: a switch configured to switch a transmission direction of signal light being unidirectionally transmitted in the first multi-core fiber and the second multi-core fiber, into bidirectional transmission; and an amplifier configured to amplify the signal light being bidirectionally transmitted.
