Embodiment Construction
[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0032] figure 1 It is a flowchart of a method for locating an optical cable fault in an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:
[0033] Step 101, receiving the test result of the monitored optical cable sent by the OTDR;
[0034] Step 102, calculating the length of the optical cable at the fault point according to the test results;
[0035] Step 103, locate the fault point of the optical cable according to the preset optical cable line resource data model.
[0036] Preferably, before step 101, the method further includes: when the loss of the optical cable is greater than a preset threshold value,...

The invention discloses a method and device for locating an optical cable fault, wherein the method includes: receiving the test result of the monitored optical cable sent by an OTDR; calculating the length of the optical cable at the fault point according to the test result; The data model locates the fault point of the fiber optic cable. The present invention makes up for the shortage of the existing optical cable resource shortage affecting the rapid cable fault location algorithm, improves the practicability of the optical cable location algorithm technology, and solves the problem of connection between the resource model and the fiber core monitoring data intercommunication technology, enabling users to pass This method quickly locates faults.
Description
technical field [0001] The invention relates to the technical field of optical cable transmission, in particular to a method and device for locating an optical cable fault. Background technique [0002] The transmission optical cable is the bridge of network communication. Timely detection of hidden dangers in the fiber core of the optical cable and rapid repairs have become the top priority. From the analysis of several faults, finding the geographical location of the fault point of the optical cable accounts for about half of the entire emergency repair time (especially at night and in bad weather. weather). The key factor to shorten the blocking time is to quickly locate the geographical location of the fault point and notify the emergency repair personnel of the fault information in time to shorten the blocking time to the greatest extent. Therefore, it is particularly important to use the rapid cable fault location technology to locate the cable fault point to shorten ...
