Long-focal-length non-contact test jumper device

Abstract

The invention aims to provide a long-focus non-contact test jumper device which comprises a test product, a test sleevearranged in the test product,and a long-focus non-contact jumper, wherein an optical fiber lens is fixed in a long-focus insertion core in a cementing mode, the long-focus non-contact jumper comprises a long-focus insertion core and a long-focus lens unit, the long-focus lens unit comprises a long-focus focusing lens, a test jumper with a tail handle, a focusing lens positioner, a limiting metal sleeve and a lens positioning protection part. During actual use, the test wire tail handle insertion core is inserted into a test device, the focal length of the test jumper wire with the tail handle is positioned at the front cover end, laser penetrates through the optical fiber lens to be focused, the focal point falls into the optical fiber core, and finally non-contact test operation is achieved.

Description

Technical field: [0001] The invention relates to the technical field of communication, and mainly relates to a test of an optical fiber jumper, in particular to a long focal length non-contact test jumper device. Background technique: [0002] Optical fiber communication technology has been widely used in various fields. With the increase of transmission rate and distance, the requirements for optical fiber transmission quality and optical fiber end face quality are also getting higher and higher. The existing optical fiber docking is very different from the original cable docking. The cable only needs to be in good contact, while the fiber end face docking needs to be strictly controlled in terms of up and down, left and right, front and back, and inclination angles to achieve good insertion loss requirements. Because the size of the part of the optical fiber that is actually used for light transmission is small, basically on the order of microns, it is not convenient for d...

AI Technical Summary

Problems solved by technology

[0008] It can be seen from the technical scheme of the optical fiber jumper disclosed above that the existing technology is either to add a jumper docking test equipment, or to improve the existing jumper, but none of them can provide the jumper. The test can prevent damage to the end face of the ferrule or the end face of the test product. At the same time, it can prevent the contact surface of the jumper from being polluted.

[0009] Therefore, how to provide a long focal length non-contact test jumper device, in the process of fiber jumper docking, use the method of non-contact test jumper, so as to prevent From the actual problem of damage to the end face of the test ferrule or damage and contamination of the end face of the test product due to docking for operation
