Abstract

The invention discloses an intelligent optical time domain reflectometer for optical cable operation and maintenance, which includes a micro-processing chip, a pulse signal generating unit, a light-emitting diode, an optical coupler and a photoelectric detection unit, a serial port to 2G communication module, an alarm unit and a positioning unit The module, the micro-processing chip, the pulse signal generating unit and the light-emitting diode are electrically connected in sequence; the incident light emitted by the light-emitting diode enters the optical fiber through the optical coupler; the optical coupler is connected with the optical fiber; the reflected light in the optical fiber enters the photoelectric detection unit through the optical coupler ; The photoelectric detection unit, the serial port to 2G communication module, the alarm unit and the positioning module are respectively electrically connected to the micro-processing chip. In addition to detecting the optical fiber, the invention also has an alarm function and a positioning function, which provides convenience for workers and increases work efficiency. At the same time, the analysis results are reported to the system through the serial port to 2G communication module, and the "big data" analysis of the optical fiber can be performed in the background, which is conducive to the unified development of optical fiber maintenance work.

Description

technical field [0001] The invention relates to the field of positioning of communication optical cables, and more particularly relates to an intelligent optical time domain reflectometer for operation and maintenance of optical cables. Background technique [0002] Optical Time Domain Reflectometer is a precise optoelectronic integrated instrument made of Rayleigh scattering and Fresnel reflection when light is transmitted in optical fiber. It is widely used in the maintenance and construction of optical cable lines. , can measure fiber length, fiber transmission attenuation, connector attenuation and fault location, etc. It is an important tool in the hands of maintenance personnel. However, with the increase of maintenance tasks, the expansion performance of existing optical time domain reflectometers is insufficient, and cannot fully meet the work needs of maintenance personnel, which affects work efficiency. Contents of the invention [0003] The invention overcomes ...
