    • Optical transceivers have loopback and pass-through paths for diagnosing transceiver components and optical networks connected to the optical transceiver or for routing data out of the transceiver in a pass-through mode. The loopback paths are selectively configured so that a selected number of the components in the transceiver are included in the loopback path. Where more than one loopback path is present, a network administrator can select which components will be included in a particular test so that, depending on whether a signal is returned on the loopback path as intended, the network administrator can determine which components are operating correctly and which are faulty. The loopbacks can be configured to run on the electrical side of the transceiver from input port to output port or on the optical side from receiver to transmitter. The pass-through paths can be used to connect the transceiver to other devices.
    • 光收发器具有环回和通过路径,用于诊断连接到光收发器的收发器组件和光网络,或者以直通模式将数据路由收发器。 选择性地配置环回路径,使得收发器中的选定数量的组件包括在回送路径中。 在存在多个环回路径的情况下,网络管理员可以选择哪些组件将包含在特定测试中,以便根据是否根据预期在回送路径上返回信号,网络管理员可以确定哪些组件正确运行 哪些是错误的。 可以将环回配置为在收发器的电源侧从输入端口到输出端口或从光接收器到发送器运行。 直通路径可用于将收发器连接到其他设备。
