The optical transmission system is the carrier of the power service channel

and the current post-event passive fault repair operation and maintenance mode is not enough to meet the needs of the operation and maintenance work

while the traditional proactive hidden danger prevention mode is mainly manual periodic inspection

in which the optical path performance inspection needs a lot of manpower. In this paper

the abundant northbound interface of the dedicated network management is used to collect data

design the complete optical section object and the abnormal optical path judgment algorithm

develop the automatic inspection tool of the power optical transmission system

automatically output the inspection results

and give an early warning to the abnormal optical path

so as to find hidden dangers in time to avoid the occurrence of faults and improve the level of independent operation and maintenance.
