Embodiment 1
[0031] see figure 1 As shown, this embodiment provides a method for automatically adjusting the optical power of a fiber optic cable based on an optical channel path, and the method includes the following steps:
[0032] Step A, for the network elements included in the OTN network that needs to be automatically adjusted for fiber and cable optical power, construct an adjustment node object; for the fiber and cable links between each network element in the OTN network that needs to be automatically adjusted for fiber and cable optical power, Constructs an adjustment fiber object. In actual operation, the node object is adjusted with the parameters related to wavelength and line power in the node and the node; the fiber cable object is adjusted with the cable parameters and link structure. Among them, the constructed adjustment node object includes signal monitoring and adjustment parameters corresponding to each type of optical amplifier disk and optical monitoring disk contai...
Embodiment 2
[0038] A method for automatically adjusting the optical power of a fiber cable based on an optical channel path provided in this embodiment has the same basic steps as in Embodiment 1, except that in step B of the method, the fiber cable is constructed by analyzing the OCh and OMS paths The specific process of the link optical power adjustment object includes:
[0039] Step B1, establish the end-to-end OCh object from the source node to the sink node, construct the OCh path routing data; analyze and decompose the OCh path routing data, and obtain the optical synthesis / demultiplexing disk, optical add / drop multiplexing disk, and wavelength selection disk, to This is the segmentation point to segment the OCh path routing data, and construct the OMS information in segments. Wherein, the constructed OCh route data includes all disks passed by the OCh route; the constructed OMS information includes position information of the OMS start and end points in the OCh route.
