Embodiment Construction

[0018] The technical solution of the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] This embodiment first provides a long-distance optical fiber detection application scenario, figure 1 It is a schematic diagram of the application scenario of long-distance optical fiber detection in the embodiment of the present application, such as figure 1 As shown, the target node on the optical fiber 101 to be tested can send a detection request to the computer device, and the computer device responds to the detection request and sends out a first optical signal 102 and a second optical signal 103 from both ends of the optical fiber 101 to be tested respectively. The optical signal 102 propagates on the optical fiber 101 to be tested to form a first sampling sequence {(36dB, 1), ..., (31dB, 25), ..., (26dB, 50), ..., (21dB, 75), ... ..., (16dB, 100), ..., (11dB, 125), ..., (6dB, 150), ...}; the second o...

Abstract

The embodiment of the invention discloses a long-distance optical fiber detection method, device, equipment and system and a storage medium. The method comprises the following steps: in response to adetection request of a target node on a to-be-detected optical fiber, determining a first sampling sequence and a second sampling sequence which are respectively formed by propagation of a first optical signal and a second optical signal which are respectively emitted from two ends of the to-be-detected optical fiber through an OTDR on the to-be-detected optical fiber; determining the total lengthof the to-be-detected optical fiber; and generating a detection result according to the first sampling sequence, the second sampling sequence and the total length, and sending the detection result tothe target node. The method comprises the following steps: determining a first sampling sequence and a second sampling sequence formed by respectively propagating a first optical signal and a secondoptical signal which are respectively emitted from two ends of the to-be-detected optical fiber through the OTDR on the to-be-detected optical fiber; and generating the detection result of the to-be-detected optical fiber by combining the total length of the to-be-detected optical fiber, so that full-coverage detection of the to-be-detected optical fiber can be realized when the optical fiber is too long, and the reliability of optical fiber detection is improved.

Description

technical field [0001] The embodiments of the present application relate to computer technology, and relate to but are not limited to a long-distance optical fiber detection method, device, device, system, and storage medium. Background technique [0002] When constructing and maintaining an optical cable line, an optical time-domain reflectometer (OTDR) is usually used to test the characteristics of the optical fiber in the optical cable. OTDR is also an important device in the online monitoring system of optical communication network, and the dynamic range is one of the important technical indicators of OTDR. The larger the dynamic range of the OTDR, the longer the distance of the optical communication line that can be monitored. However, the dynamic range of OTDR may not be able to meet the detection requirements of long-distance optical fiber lines. Facing lines exceeding a certain length, OTDR will not be able to detect the information of remote optical fibers. Conte...
