Embodiment 1

[0053]At present, the industry judges the breakpoint of optical cable fault mainly depends on OTDR (Optical Time-domain Reflectometer, optical time domain reflectometer) equipment and single board with OTDR function. Most of the core patents of OTDR equipment are in the hands of Japanese, European and American enterprises. The optical cable fault location method provided in the example belongs to the problem of calculating the physical breakpoint at the software algorithm level. The implementation cost is low, and the effect can be expected to be good. It can make up for the technical gap in this field in the domestic industry and break through the patent monopoly.

[0054] Specifically, the optical cable fault location method of the embodiment of the present invention is applicable to an optical cable transmission network, which may include at least one pair of optical transmission components, such as two pairs, three pairs or four pairs of optical transmission components, see ...

Abstract

The invention discloses an optical cable fault location method, device and electronic equipment. The optical cable fault location method, compared with the need to use external dedicated hardware equipment to locate the optical cable fault, not only increases the hardware equipment but also takes a lot of time, the optical cable fault location method provided by the present invention does not need to increase external hardware, and directly uses the optical cable transmission network The existing pair of optical transmission components can transmit frame signals to each other, and the network management needs to monitor and manage the characteristics of the optical transmission components to obtain the number of frames transmitted between a pair of optical transmission components and the complex number of the last frame. The frame value, and the multiframe value of the target frame sent by the target component on the sending side when the last frame is received, combined with the length of each frame signal in the optical cable transmission network, determines the fault area between a pair of optical transmission components In other words, by upgrading the software level in the optical cable transmission network, that is, the purpose of locating the optical cable fault can be quickly realized from the software level.

Description

technical field [0001] The invention relates to the technical field of optical cable transmission, in particular to an optical cable fault location method, device and electronic equipment. Background technique [0002] When a fault such as a breakpoint occurs in the optical cable, it is often necessary to detect and monitor the entire section of the optical cable with the help of special optical detection equipment in order to determine the location of the breakpoint fault. [0003] However, fault location with the help of special detection equipment not only needs to add special hardware equipment outside the optical cable transmission network, but also time-consuming detection. Contents of the invention [0004] In order to solve the problems of adding special hardware equipment and time-consuming detection for optical cable fault location, the present invention provides an optical cable fault location method, device and electronic equipment. [0005] In a first aspect,...
