Multifunctional optical cable detection device and method

Abstract

The invention relates to the technical field of optical cable detection, in particular to a multifunctional optical cable detection device and method. The multifunctional optical cable detection device comprises a transmitter and a receiver. The transmitter comprises a controller, a low-frequency alternating current signal generator, an OTDR detection assembly and an optical cable general survey detection assembly. The controller is used for selecting and configuring the transmitter into a function I mode, a function II mode and a function III mode. Routing direction or burial depth information of a target optical cable can be obtained by matching with the receiver in the function I mode. Optical fiber breakpoint information can be obtained in the function II mode. The target optical cablecan be found from a plurality of optical cables in the function III mode. The beneficial effects of the multifunctional optical cable detection device and method are that when optical cable detectionis carried out, only one multifunctional optical cable detection device needs to be purchased, various devices do not need to be purchased at the same time, and the repeated investment is reduced. Meanwhile, a client only needs to use one multifunctional optical cable detection device, so that the complexity of detection work is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of optical cable detection, in particular to a multifunctional optical cable detection device and method. Background technique [0002] Current optical cable detection devices mainly include three types, optical time domain reflectometer (OTDR), optical cable census instrument and cable detector (also called pipeline instrument). [0003] Among them, OTDR is an instrument used to detect the uniformity, defect, fracture, joint coupling and other properties of optical fiber. By reflecting a beam of light to the optical fiber, and timing the time when the light is sent out and then reflected back from the breakpoint, the distance between the breakpoint and the breakpoint is calculated. The distance from the sending point. This device can accurately query the length of the optical fiber breakpoint from the source end, but it cannot determine the general direction of the optical cable, let alone detect the routi...
