A tester based on optical cable otdr test

Abstract

The invention discloses a tester based on optical cable OTDR testing, and relates to the field of optical cable testing instruments. Anti-dropping devices and cleaning devices are provided on both sides of the connection between the connecting joint and the optical cable plug, and the upper end of the tester body is connected with a protective cover. The invention presses two buttons, the crank turns the two clamping blocks open, inserts the optical cable plug into the connection joint, after releasing the button, the reset spring resets, and the two clamping blocks are fixed to the outer wall of the optical cable plug to prevent the optical cable plug from falling off, Easy to operate; at the same time when the button is released, the clamping block squeezes the elastic airbag to make the cleaning liquid in it clean the optical port; when not in use, the protective cover is turned over and closed with the upper end of the tester body to make the buckle and the buckle groove. The elastic air bag is clamped by the clamping block, the protective cover is fixed, and the connecting joint and the anti-dropping device are covered and protected.

Description

technical field [0001] The invention relates to the field of optical cable testing instruments, in particular to a testing instrument based on optical cable OTDR testing. Background technique [0002] Rayleigh scattering and Fresnel reflection occur when light propagates in an optical fiber. OTDR is a high-tech, high-precision optoelectronic device made by using the characteristics of light to collect backscattering and reflection of light pulses in the path. Integrated instrument. During the detection and use of the optical cable by the OTDR test instrument, the optical cable needs to be connected to the connection end of the OTDR test instrument. The traditional OTDR test instrument usually connects the optical cable connector to the connection end of the instrument by means of screw connection. Frequent connection and disassembly It is easy to cause damage to the threaded teeth, which affects the use of the equipment; the connection end of the traditional OTDR test instr...

AI Technical Summary

Problems solved by technology

During the detection and use of the optical cable by the OTDR test instrument, the optical cable needs to be connected to the connection end of the OTDR test instrument. The traditional OTDR test instrument usually connects the optical cable connector to the connection end of the instrument through a threaded connection. Frequent connection and disassembly It is easy to cause damage to the threaded teeth, which affects the use of the equipment; the connection end of the traditional OTDR test instrument is usually exposed to the outside, and the anti-impact performance is poor, which is easy to cause damage to the connection end, and the exposed connection end is used to emit laser light. Contaminated by dust, the noise of the tester becomes louder, the curve is bad, and the test results are affected
