In this embodiment, since the jitter degree may be represented by a standard deviation, a requirement of the preset jitter degree may be set as a preset standard deviation threshold, and the standard deviation is compared with the preset standard deviation threshold to determine whether the jitter degree meets the requirement of the preset jitter degree, for example, in some embodiments, the standard deviation threshold may be set to 0.3, and when the jitter degree represented by the standard deviation is greater than or equal to 0.3, the stability degree of the receiving-end network element and the originating-end network element during optical transmission is poor, which may cause a problem and may require maintenance by a maintenance person, so that a step of determining a second jitter amplitude of the receiving-end network element during optical signal transmission may be performed according to a second current output optical power and a second historical output optical power.

And the second target output optical power is a second current output optical power which is out of a second threshold range. The second amplitude sum value may be a sum of differences of a second target output optical power outside a second threshold range and the second threshold range. For example, in some embodiments, when the second threshold range is 1 to 3DB and the second output optical power is 4DB, the second output optical power is the second target output optical power, the second amplitude of the second target output optical power may be 1DB, and the second amplitude sum value may be a sum of the second amplitudes.

when the jitter degree ratio is larger than the jitter amplitude ratio, representing the jitter frequency of optical network transmission as a main problem, comparing the jitter degree with the jitter degree of a sending end:

if the jitter degree is less than or equal to the jitter degree of the transmitting end, the detection result is that the network element of the transmitting end is abnormal;

when the jitter degree ratio is smaller than or equal to the jitter amplitude ratio, representing the jitter amplitude of optical network transmission as a main problem, comparing a first jitter amplitude with a second jitter amplitude:

In this embodiment of the present application, when the jitter degree and the originating jitter degree are zero, and the first jitter amplitude and the second jitter amplitude are not zero, or when the jitter degree or the originating jitter degree are zero, and the first jitter amplitude or the second jitter amplitude is zero, or when the jitter degree or the originating jitter degree are not zero, and the first jitter amplitude or the second jitter amplitude is zero, the first jitter amplitude and the second jitter amplitude are compared:
