    • An optical communication system, where in an optical transmission apparatus arranged on a transmission side of respective repeating sections, an OSC optical amplifier is provided on an OSC light optical path between from an OSC transmitter to a multiplexer, and the OSC optical amplifier is controlled so that the power of OSC light transmitted on the transmission path becomes a previously set target value. As a result the OSC light is amplified by a different amplifying device to that for the main signal lights at the time of transmission. Therefore even in the case where the span losses are large, OSC light can be reliably received by the optical transmission apparatus on the reception side.
    • 一种光通信系统,其中在配置在各重复部分的发送侧的光传输装置中,OSC光放大器设置在从OSC发射机到多路复用器之间的OSC光路上,并且OSC光放大器被控制为 在传输路径上传输的OSC光的功率变成预先设定的目标值。 结果,OSC光被不同的放大装置放大到在传输时主信号灯的放大装置。 因此,即使在跨度损耗大的情况下,也可以通过接收侧的光发送装置可靠地接收OSC灯。
