Optical fiber end face 8-degree cutting pen

Abstract

The invention relates to the technical field of optical fiber transmission, in particular to an optical fiber end face 8-degree cutting pen which comprises an optical fiber, a transparent window, a ceramic ferrule, an optical fiber grating and a gate region, the transparent window is arranged in the optical fiber, the ceramic ferrule is arranged in the transparent window, the optical fiber grating is arranged in the ceramic ferrule, and the gate region is arranged in the middle of the outer surface of the ceramic ferrule. The right side in the transparent window is provided with an optical fiber end face, the inclination of the optical fiber end face is 8 degrees, the bottom of the optical fiber end face is provided with a blade, the top of the side face of the optical fiber end face is fixedly connected with a first rubber sheet, and the bottom of the side face of the optical fiber end face is fixedly connected with a second rubber sheet. According to the 8-degree cutting pen for the optical fiber end face, the instability of manual beveling and the risk of optical fiber breakage caused by optical fiber cutting can be mainly solved, the excellence and the consistency of end face reflection can be improved, grating damage in the production process can be reduced, compared with an existing PC or UPC, the return loss is 50-55 dB, the return loss of an inclined 8-degree optical fiber APC is 60-65 dB, and the reflection is very small.

Description

technical field [0001] The invention relates to the technical field of optical fiber transmission, in particular to an 8° cut pen on the end face of an optical fiber. Background technique [0002] Optical fiber end-face treatment, also known as end-face preparation, is a key process in optical fiber technology, mainly including three steps: stripping, cleaning and cutting. The quality of the end face directly affects the pump light coupling efficiency and laser output power of the fiber laser. [0003] Return loss is called reflection loss, which is the reflection of the cable link due to impedance mismatch, and is the reflection of a pair of lines themselves. The mismatch mainly occurs in the connector, but it may also occur in the place where the characteristic impedance changes in the cable. The return loss of the 8-degree connector is usually better than that of the general connector. The general return loss is -45dB, and the 8-degree The return loss is -60dB. [0004...

Problems solved by technology

The mismatch mainly occurs in the connector, but it may also occur in the place where the characteristic impedance changes in the cable. The return loss of the 8-degree connector is usually better than that of the general connector. The general return loss is -45dB, and the 8-degree Return loss is -60dB

[0004] When the existing light is cut, most of them are cut manually, and the artificial oblique cutting has the risk of breaking the optical fiber due to instability. Therefore, it is necessary to design a cutting tool to reduce the damage of the grating during the production process.
