    • A wavelength-division multiplexing optical communication system and a method for measuring optical performance of an output signal for the system. The optical communication system includes: a service-provider device; a local node; and a plurality of subscriber devices. The service-provider device includes: a plurality of first optical transceivers; a first optical multiplexer/demultiplexer (OD/OM) connected to the plurality of first optical transceivers; and a seed-light source providing seed light. Each subscriber device includes a second optical transceiver. The local node connects the service-provider device and the plurality of subscriber devices to each other using a DWDM link comprising: a second multiplexer/demultiplexer (OD/OM); and a single-mode optical fiber for transmission. Here, the optical intensity of an output signal of the second optical transceiver is determined by compensating for the value of the loss caused when the output signal passes through the second OD/OM of the local node.
    • 一种波分复用光通信系统和用于测量该系统的输出信号的光学性能的方法。 光通信系统包括:服务提供者设备; 一个本地节点; 和多个订户设备。 服务提供者设备包括:多个第一光收发器; 连接到所述多个第一光收发器的第一光复用器/解复用器(OD / OM); 和提供种子光的种子光源。 每个用户设备包括第二光收发器。 本地节点使用DWDM链路将服务提供商设备和多个用户设备彼此连接,包括:第二多路复用器/解复用器(OD / OM); 和用于传输的单模光纤。 这里,通过补偿当输出信号通过本地节点的第二OD / OM时引起的损耗的值来确定第二光收发器的输出信号的光强度。
