Multi-core optical fiber connector

Abstract

The invention relates to a multi-core optical fiber connector, which includes a plug, an adapter and several optical fibers connected to the plug. Each optical fiber is provided with an independent ferrule, and the end surface is ground into a spherical surface. The ferrule is fixed on a tailstock. The adapter is provided with several docking boxes for connecting optical fibers, each of which is fixed with a guiding device for ensuring the accuracy of butt jointing of the fiber ferrule, and the plug includes fixing parts for arranging several optical fibers and locking and fixing There are several cavities corresponding to the docking box of the adapter in the fixed part, and each ferrule protrudes from the cavity of the fixed part and connects to the guide device of the adapter. In the multi-core optical fiber connector of the present invention, the docking of the several optical fibers does not affect each other, and the docking is completed independently, and the optical fibers are connected by a spherical surface, which can greatly improve the light guiding performance of the optical fiber connector and reduce the insertion loss and echo of the optical fiber Loss, and can improve space utilization in dense fiber connection occasions.

Description

【Technical field】 [0001] The invention relates to an optical fiber connector, in particular to a high-precision optical fiber connector capable of integrating multiple optical fibers. 【Background technique】 [0002] With the deployment and application of fiber-to-the-home (FTTH) around the world, how to quickly establish a large number of home optical cable connections scattered like capillaries has become an urgent problem to be solved in the industry. Because when the number of users reaches a certain level, the existing networking methods are no longer able to meet the time requirements for users to open services. In the fiber-to-the-home project, in order to meet the needs of high-density and high-efficiency interconnection wiring in high-speed and large-capacity fiber optic communication systems, multi-core fiber optic connectors have emerged as the times require. [0003] At present, multi-core optical fiber connectors, such as the MPO type developed by NTT Corporatio...

Problems solved by technology

However, once the flatness of the fiber end face processing is not accurate enough, the planes of the fiber end faces cannot be tightly fitted, or when the end face planes are squeezed and deformed due to too tight fit between the fiber end faces, the insertion loss of light will be very large

Moreover, because the MPO multi-core optical fiber connector uses a flat contact method to connect the optical fiber, the flat optical fiber end is more sensitive to dust, which is prone to Fresnel reflection and increases the return loss of optical fiber transmission.
