The invention relates to a method of optical cable range finding with an optical cable tracker and an optical cable tracker. The optical cable tracker comprises a light source, an optical coupler, a phase modulator, a delay fiber and an optical signal demodulation module. According to the invention, knocking and disturbance are carried out towards the optical cable, the corresponding interference produced in the light of the optical cable can be used to recognize which one the optical cable is and the distance from the knocking point to the local side and it is convenient to maintain the optical cable.
Description
technical field [0001] The invention relates to the field of optical cable ranging, in particular to a method for measuring optical cable distance by using an optical cable tracker and the optical cable tracker. Background technique [0002] In order to facilitate operations such as maintenance and modification of optical cables, usually the optical cables connected between two telecommunications offices will be affixed with identified labels. That is, through the identification on the label, the maintenance personnel can know the information including the source of the optical cable. However, in actual work, technicians find that the label with the identification is easy to lose, and once the label is lost, it is difficult for the technician to determine which office end has connected the optical fiber. [0003] At present, the existing methods for identifying optical cables are as follows: [0004] 1. Use physical force to pull the optical cable; [0005] 2. Through ele...
