Abstract

The invention relates to the technical field of fiber switches, and provides a pulsed light fiber switch state detection method. The detection method includes the following steps: acquiring the pulse peak position of each fiber switch node sensor in a fiber switch sensor network; calculating the difference between the numerical values of the pulse peak position of each fiber switch node sensor in the data of the current sampling period and in the data of the previous sampling period; if the difference is smaller than or equal to a preset first percent of the data of the pulse peak position of each fiber switch node sensor in the data of the previous sampling period, keeping the state of the corresponding fiber switch node sensors unchanged; and if the difference is greater than the first percent of the data of the pulse peak position of each fiber switch node sensor in the data in the previous sampling period, modifying the recorded state of the corresponding fiber switch node sensors. The technical problem that it is difficult to find enough communication rooms to place signal analysis devices used for processing reflected light signals in nearby areas is solved. The detection network system is simplified. The efficiency of detection system maintenance is improved.

[0001] 【Technical field】 [0002] The invention relates to the technical field of optical fiber switches, in particular to a method for detecting the state of a pulsed optical fiber switch. [0003] 【Background technique】 [0004] The optical cable transfer box is a transfer device that provides optical cable termination and jumper connection for the backbone layer optical cable and the distribution layer optical cable. After the optical cable is introduced into the optical cable transfer box, after being fixed, terminated, and distributed, the backbone layer optical cable and the distribution layer optical cable are connected using a jumper fiber. It is mainly used in the optical cable communication network to connect the main optical cable and the branch optical cable, and to perform termination protection, connection and dispatch management on optical cables and optical fibers. [0005] With the promotion of fiber-to-the-x (abbreviated as: FTTx) technology and the expansion...
