Description

technical field [0001] The invention relates to an optical fiber fault detection method. Background technique [0002] At present, optical fiber communication is an important infrastructure of power communication network. However, in actual operation, communication optical fibers often fail due to the influence of natural environments such as lightning or human operations such as improper installation and maintenance. Traditional optical fiber fault detection mostly uses OTDR (Optical Time Domain Reflectometer) for detection, but this method has the following errors: the first error, due to the technical level of the OTDR tester itself, the combined connection of optical fiber models with different parameters, etc. Causes the error of the OTDR tester itself; the second type of error, OTDR can only detect the length of the fiber at the fault point in theory, but in actual engineering, due to various factors such as fiber bending, arc sag, residual cable, interface loss, etc....
