Description

TECHNICAL FIELD

[0001] The utility model relates to optical fiber detection device technical field, concretely relates to a kind of optical fiber signal on-off testing device. BACKGROUND

[0002] Optical fiber, as the abbreviation of optical guide fiber, is an indispensable important component in modern communication system. It is made of glass or plastic, and uses the total reflection principle of light in fiber to transmit optical signals. Optical fiber is widely used in long-distance communication, local area network construction and various data transmission fields due to its high bandwidth, low loss and strong anti-interference ability. However, during use, optical fiber may have breakpoints due to aging, wear and tear, improper installation or external factors (such as construction damage, natural disasters, etc.). These breakpoints not only cause leakage or interruption of optical signals, affecting the stability and reliability of information transmission, but also may cause communication failure and even threaten information security. Therefore, it is particularly important to detect the breakpoints of optical fiber. Optical fiber signal on-off testing device emerges as the times require, aiming to timely detect and locate the breakpoints in optical fiber through efficient and accurate detection means, so as to ensure the normal operation of optical fiber communication system.

[0003] The distribution type optical fiber breakpoint detection device with publication number CN216717770U can gradually fix the optical fiber by clamping plate, and the second handle can be rotated according to the diameter of the optical fiber when the optical fiber is fixed. The second handle drives the threaded rod to rotate, and the threaded rod drives the first sliding block to move. When the detection head moves to the appropriate position, the second handle is no longer rotated, and then the motor is started. The motor drives the reciprocating screw rod to rotate, and the reciprocating screw rod drives the moving strip to reciprocate. Under the action of the moving strip, the detection head reciprocates. At this time, the detection head can detect the optical fiber clamped and fixed by the clamping plate, solve the problem that the traditional optical fiber is not convenient to detect the breakpoint, and achieve the purpose of saving time and effort.

[0004] Although the above-mentioned distribution type optical fiber breakpoint detection device can detect the optical fiber after being fixed by clamping plate, ensuring the stability during detection, the detection device does not set a closed detection space, and the entire detection operation is exposed to the external environment. External environmental factors can affect the detection results to some extent.
