A magnetic fiber optic coupling device

Abstract

The invention relates to a magnetic optical fiber coupling device which comprises an inserting head and an inserting tail which are inserted each other, wherein the inserting head comprises a first plugging part and a first connecting part, the inserting tail comprises a second plugging part and a second connecting part, and both the first plugging part and the second plugging part are magnetic and are opposite in magnetism; the first inserting part comprises a first optical fiber compound body and a tube wall which is arranged out of the first optical fiber compound body; and the second inserting part comprises a second optical fiber compound body and a sleeve which is arranged out of the second optical fiber compound body. The coupler provided by the invention is high in plugging speed, high in durability, good in optical fiber alignment property and high in light conductivity, and can axially rotate randomly after connection without affecting the light conductivity; and by way of inserting or combining each other in a concave-convex manner and the like for matched connection, the stability and reliability of the coupling mode are greatly increased, and the light conductivity is further greatly improved correspondingly.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a magnetic fiber coupling device. Background technique [0002] Optical fiber coupler is a device for detachable and movable connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and make It intervenes in the optical link so that the impact on the system is minimized. According to the difference of the coupled optical fiber, there are the following classifications: SC fiber coupler: applied to the SC fiber interface, it looks similar to the RJ-45 interface, but the SC interface is flatter, the obvious difference is the contact inside, if It is 8 thin copper contacts, it is RJ-45 interface, if it is a copper column, it is SC optical fiber interface. LC fiber optic coupler: It is applied to LC f...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a magnetic optical fiber coupling device, which solves the problem that the existing coupler needs to be tightly connected by rotating, the coupling efficiency is greatly affected by the number of rotations and force, and the number of connections is large. Afterwards, it is easy to wear the end face, resulting in increased loss, slow connection speed, and inability to rotate after connection.
