Multi-core optical fiber connection structure

Abstract

The invention discloses a multi-core optical fiber connector, comprising a multi-core optical fiber capillary sleeved on a multi-core optical fiber, connection optical fibers, a connection optical fiber capillary sleeved on the outside of the connection optical fibers and an optical fiber elastic sleeving, wherein the quantity of the connection optical fibers is identical to that of the cores of the multi-core optical fiber, the distribution of the connection optical fibers is identical to that of the cores of the multi-core optical fiber and the outer diameter is D; the optical cable elastic sleeving sleeves the outside of the multi-core optical fiber capillary and the connection optical fiber capillary; when the multi-core optical fiber capillary is closely abutted against the connection optical fiber capillary, the multi-core optical fiber is abutted against the connection optical fibers; the multi-core optical fiber is in butt joint with the connection optical fibers through rotating the connection optical fibers; and the optical fiber elastic sleeving is fixed with the connection optical fiber capillary through glue and the multi-core optical capillary. Through the technical scheme of the multi-core optical fiber connection structure, two capillaries are abutted against and then realize the butt joint between the multi-core optical fiber and the connection optical fibers through rotating, and the loss value is minimum.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to a multi-core optical fiber connector. Background technique [0002] Optical fiber connector is a device for detachable 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 due to its The impact on the system caused by the intervention of optical links is minimized, which is the basic requirement of optical fiber connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems. [0003] In order to meet the needs of high-density and high-efficiency interconnection wiring in high-speed and large-capacity optical fiber communication systems, multi-core optical fibers are used more and more widely, that is, there are mult...
