一种光分插复用器及其控制方法、收发机技术

本发明专利技术实施例提供了一种光分插复用器，包括：多个可调光分插复用器T‑OADM，每个T‑OADM包括第二波长控制单元和两个光栅辅助滤波器GAF；第二波长控制单元与第二GAF连接；第一GAF的下载端口与第二GAF的输入端口连接，第一GAF的上传端口与第二GAF的输出端口连接；第一GAF的输入端口接收多个波长的光波，第一GAF通过第一GAF的下载端口将第一光波传输至第二GAF的输入端口；第二波长控制单元按照波长漂移的第一幅度改变第二GAF的下波光谱，得到第一光波响应；第二GAF的下载端口输出第一目标带宽的第一目标光波。本发明专利技术实施例还提供了一种光分插复用器的控制方法、收发机。

An optical add drop multiplexer and its control method and transceiver

The embodiment of the invention provides an optical add-drop multiplexer comprising a plurality of tunable optical add-drop multiplexers T_OADM, each T_OADM comprising a second wavelength control unit and two grating auxiliary filters GAF, a second wavelength control unit connected to a second GAF, a download port of the first GAF connected to an input port of the second GAF, and a first GAF connected to an input port of the second GAF. The upload port is connected with the output port of the second GAF; the input port of the first GAF receives multiple wavelengths of light, and the first GAF transmits the first light to the input port of the second GAF through the download port of the first GAF; and the second wavelength control unit changes the downwave spectrum of the second GAF according to the first amplitude of the wavelength shift to obtain the first. Light wave response; second GAF download port outputs the first target bandwidth of the first target light wave. The embodiment of the invention also provides a control method and transceiver for an optical add drop multiplexer.
