Abstract

The invention discloses a data processing method, a data processing device and equipment and a computer readable storage medium. The method comprises the following steps: receiving optical fiber backward Rayleigh scattering power data measured by an optical time domain reflectometer OTDR; carrying out average processing, low-pass filtering processing and logarithmic transformation processing on the data to obtain a first OTDR curve; obtaining an event i, an occurrence position range ai-bi of the event i and a position range an-bn of a possible event n; and carrying out event accurate positioning to obtain an accurately positioned event position and an occurrence position range thereof. According to the invention, optical fiber attenuation and abnormal events are monitored separately; during attenuation monitoring, a large dynamic range of attenuation monitoring can be realized through low-pass filtering processing with relatively narrow passband width; the abnormal event is accuratelypositioned through accurate event positioning; and the attenuation monitoring range and the event monitoring range of the OTDR are increased, so that the spatial resolution of the event is not deteriorated.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data processing method, device and equipment, and a computer-readable storage medium. Background technique [0002] With the development of optical communication technology, optical fiber has become the main transmission medium of modern communication. The management and maintenance work of optical fiber network is becoming more and more heavy. It is of great significance to monitor the optical fiber link, find link faults in time, and accurately locate the faults to ensure the safe and stable operation of the communication network. [0003] OTDR (Optical Time-Domain Reflector, Optical Time Domain Reflector) is the most common optical fiber line measurement instrument, which obtains the attenuation and breakpoint of the optical fiber line by detecting the Rayleigh backscattered light of the optical fiber under test. Dynamic range and event resolution are t...
