The invention discloses an optical cable route identification and fault diagnosis system and method. The system comprises a pulse light source, a circulator, a communication optical fiber, a photoelectric detector and a plurality of data collectors, wherein the plurality of data collectors are used for generating physical signals containing position data and unique identification information codesand acting on the outer layer of the communication optical fiber so as to enable the communication optical fiber at the position to return optical wave signals which are strained according to a certain rule; a main control module is used for controlling the output of the pulse light source, controlling the receiving of the photoelectric detector and identifying the light wave signals strained according to rules. According to the system disclosed in the embodiment of the invention, optical fiber positioning, optical fiber sensing, fault diagnosis and optical line routing are combined; positiondata of the data collector and the unique identification information codes are combined and encoded and then strain excitation is performed on the outer layer of the optical cable so that unique identity identification and geographical position automatic positioning of optical line routing positioning can be realized by utilizing the sensing characteristic of the optical fiber, and optical cablerouting fault diagnosis can be realized by repeatedly measuring the waveform intensity twice before and after measurement.
Description
technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical cable routing identification and fault diagnosis system and method. Background technique [0002] Existing optical cable routes need to be manually collected, and the fault diagnosis of the optical cable needs to rely on the segmented optical cable splice box to indicate the fault. It is very inconvenient to deploy the optical cable splice box to segment the optical cable with a long distance. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an optical cable route identification and fault diagnosis system, which can realize unique identification of data collectors, automatic geographic location positioning and fault diagnosis; the present invention also provides an optical cable route identification and fault diagnosis meth...
