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,...

Abstract

The invention discloses an optical cable fault location method and a device thereof. The method contains the following steps: a measurement result of a monitored optical cable that is sent by an OTDR is received; length of an optical cable with a fault point is calculated according to the measurement result; and the fault point of the optical cable is located according to a preset optical cable line resource data model. According to the invention, the defect that insufficiency of present optical cable resources influences quick location algorithm of optical cable faults is solved, and practicality of an optical cable location algorithm technology is improved. Meanwhile, the connection problem of a resource model and a fiber core monitoring data intercommunication technology is solved, and users can rapidly locate faults through the above method.

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 ...
