    Abstract: A node of an optical transport network system transmits optical wavelengths to an adjacent node through an operational line. An apparatus for protection switching of the optical transport network system transmits only an optical channel with a fault among a plurality of optical channels composed of flexible optical channel data units in an optical wavelength of the operational line, via a reserve line.

    Abstract translation: 光传输网络系统的节点通过操作线路将光波长传输到相邻节点。 光传输网络系统的保护切换装置仅通过备用线路在操作线路的光波长中的柔性光通道数据单元组成的多个光通道中仅发送具有故障的光信道。
