Abstract

The application relates to an optical fiber jumper wire joint and a detection device thereof, which solve the problem of laser leakage detection. The material of the ferrule is transparent or partially transparent to the laser light being transmitted, and the glue bonding the optical fiber and the ferrule also has transparent or partially transparent properties. Laser which cannot enter the transmission optical fiber or leaks from the transmission optical fiber enters the transparent adhesive glue and then enters the transparent insertion core, and the laser can be detected by a detector after being transmitted to the surface of the insertion core, so that the problem that the light intensity of the leaked laser is difficult to determine is solved. When the leaked laser is too much and the stability of the jumper structure is possibly influenced, the optical fiber is judged to be an unqualified product and is replaced, so that the damage caused by sudden stop of the laser in use is avoided. Thus, the problem of light intensity judgment of leakage light in the optical fiber jumper is solved.

Description

Optical fiber jumper wire joint and detection device thereof

Technical Field

The application relates to the technical field of optical fiber transmission and laser detection, in particular to an optical fiber jumper connector and a detection device thereof.

Background

The optical fiber jumper structure is a technology developed from the field of connection of communication optical fibers, has the characteristics of simple structure, quick and convenient connection, stable structure, small loss and the like, and has wide application in the field of optical fiber communication.

With the increasing application of optical fibers in the field of laser transmission, people put forward the requirement of pluggable optical fibers to meet the requirement of replacing optical fibers at any time in a practical field. Thus, the optical fiber jumper structure is introduced into the field of laser transmission. In the early days, the transmitted laser power was small, which was not a problem, but as the transmitted laser power became larger, the problem appeared.

When the optical fiber jumper structure is used for transmitting laser, a small amount of laser loss exists, the laser cannot enter the optical fiber, or the laser enters the optical fiber but does not meet transmission conditions so as to leak out in later transmission. The laser light lost at the jumper connection is not transmitted along the optical fiber, and enters the jumper structure to be converted into heat energy. Under the condition of low laser power, the heating of the material of the jumper wire is small, and the system is not damaged too much. However, under the condition of transmitting high-power laser, the leaked laser generates a large amount of heat energy to directly damage the structure of the jumper wire, so that the transmission of the laser is interrupted, and great harm is generated on the application field. For example, in medical laser surgery, the sudden interruption of laser light causes the surgery to be forcibly interrupted, seriously threatening the physical health of the patient.

Therefore, after the optical fiber patch cord is connected, the leakage degree of the laser is evaluated in real time, and the patch cord with more leaked laser is prevented from being connected into a system, so that the method becomes a significant work.

The traditional optical fiber jumper structure adopts a method of directly butting two insertion cores, the distance between the two insertion cores is very small and is in a micron order, leaked laser directly enters the insertion core of the light-receiving optical fiber, and the material of the insertion core is made of opaque materials such as ceramics or metal, so that the problem of how to detect the leaked laser is solved.
