Multicore optical fiber connector

Abstract

The invention discloses a multicore optical fiber connector which comprises a plug assembly and a socket assembly. The plug assembly is formed by an insulation casing and a plurality of plug inserting core assemblies, wherein each plug inserting core assembly comprises a ceramic inserting core seat, a spring, a spring blocking unit, a ceramic inserting core and a ceramic sleeve. The socket assembly is formed by an insulation casing and a socket inserting core assembly. The multicore optical fiber connector is characterized in that an outer spring is sleeved outside each plug inserting core assembly in the plug assembly, the front end of the plug inserting core assembly is provided with a plug front outer casing, the front end of the plug front outer casing is sleeved outside each ceramic sleeve, the tail end of the plug front outer casing is connected with each spring blocking unit, the outer edges of the spring blocking unit and the plug front outer casing are provided with annular protrusions respectively, and the outer spring is arranged between the two annular protrusions. According to the multicore optical fiber connector, the outer spring is sleeved outside each plug inserting core assembly so that axial and radial floating between the plug front outer casings and internal parts can be achieved, and insertion loss and return loss are avoided.

Description

technical field [0001] The invention relates to an optical fiber connector, in particular to a multi-core optical fiber connector. Background technique [0002] Optical fibers are increasingly used for broadband applications, including voice, video and data transmission. As a result, fiber optic communication networks include many interconnection points interconnecting multiple optical fibers. The optical fiber communication network also includes many connection terminals, which are used to extend the optical fiber communication service to users, and develop into "fiber to the curb" (FTTC), "fiber to the enterprise" (FTTB), "fiber to the user" (FTTH), " Fiber to the Premises" (FTTP), collectively referred to as "FTTx". [0003] Optical fiber connector is a device for detachable (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...

Problems solved by technology

[0005]However, due to the increasing number of ferrule components contained in the multi-core optical fiber, when the plug and socket are docked, it is inevitable that the various ferrule components will cause The accuracy of the docking between the ferrules is not good, which leads to the insertion force of the ferrule components in the case of misalignment, which becomes a hard insertion, which is easy to cause the insertion loss and return loss of the ceramic ferrule, and ultimately affects Data transmission performance after docking
