In the prior art, the optical time domain reflectometer is usually used to test the distance of the fiber core of the optical cable, and the actual position of the site is searched according to the test length. The longer the deviation is, the longer the fault location and troubleshooting time will be. If the optical cable is in normal use, it will be more difficult to confirm the position of the operating point. Usually, it is necessary to find the optical cable splice box to interrupt the optical fiber core before cutting the fiber. Test, and finally determine the length, this operation can easily cause business interruption and quality problems caused by the secondary packaging of the connector box, which has brought great trouble to users

The invention discloses an optical cable operation point positioning method and a positioning device. An operation point is positioned by comparing test curves of back scattering signal amplitudes before and after bending deformation of an optical cable, and comparison result data is displayed through a legend, so that a user can know the condition of the operation point clearly, intuitively and concisely. A user can better maintain the optical cable and take corresponding measures, the method has a strong effect on improving the business operation quality and the company value, and meanwhile, obvious economic benefits and social benefits can be generated.
Description
technical field [0001] The invention relates to a positioning method and a positioning device for an optical cable operation point, belonging to the optical signal communication testing technology. Background technique [0002] At present, communication optical cables are becoming more and more important in the construction of network power, digital China and 5G. The safety and stability of optical cable lines will directly affect the safety and reliability of communication networks. During the use of optical cable lines, failures will occur due to construction digging, vehicle and ship breaking, man-made damage, product quality, etc. During fault repair and project planning and construction, it is necessary to confirm the location of the fault point or operation point of the optical cable as soon as possible to shorten the time for fault repair or optical cable confirmation. In the prior art, the optical time domain reflectometer is usually used to test the distance of the...
