s101: and after the gain of the power amplifier single board in the light receiving direction of at least two nodes in the wavelength division system is collected, outputting the residual data.
The margin data is the difference between the maximum output optical power and the actual output optical power at the node.
Optionally, before S101, the user needs to select a node to be detected in the target wavelength division system on the network management interface, and then collects residual data of the selected node to be detected.
Optionally, before a user selects a node to be detected on the network management interface, the user needs to log in the network management interface according to user identity information, and after the login is successful, the node to be detected in the corresponding authority is selected in the target wavelength division system according to the authority of the user, wherein the user identity information may be any one that can uniquely represent the user identity information, such as a user name and a password, or fingerprint information, or face information, and the like, and the specific mode of logging in the network management interface is designed according to the user needs, and the application is not limited herein.

The actual number of optical channels that each node can expand is the difference between the number of optical channels that the system should carry and the number of optical channels that the system already carries; the optical capacity redundancy refers to that the wavelength division system reserves gain optical power which is higher than the optical power required by carrying the optical signals with the nominal channel number, namely a threshold value of bottleneck early warning.
S103: and judging whether the wavelength division system has an optical capacity bottleneck or not according to the actual number of the optical channels which can be expanded by each node and the nominal number of the optical channels which can be expanded by each node.

For example, the following steps are carried out: when the preset threshold is 2 and Δ =2, it indicates that the optical capacity of the current wavelength division system is normal, that is, no optical capacity bottleneck occurs; when 0< delta <2, the bottleneck of the optical capacity of the current prediction wavelength division system is about to occur; when Δ ≦ 0, it indicates that the current WDM optical capacity has become a bottleneck.
