Description

Single-tube double-core LC jumper wire assembly

Technical Field

The utility model belongs to the technical field of fiber optic cable's technique and specifically relates to a single tube twin-core LC jumper wire subassembly is related to.

Background

Optical fiber jumpers are used to patch wires from equipment to fiber optic cabling links. The optical fiber terminal is provided with a thicker protective layer, is generally used for connection between an optical transmitter and a terminal box, is applied to the fields of optical fiber communication systems, optical fiber access networks, optical fiber data transmission, local area networks and the like, and is used for realizing optical path movable connection, and a tail fiber is called when a plug is arranged at one end of the optical fiber terminal. Optical fiber jumpers are similar to coaxial cables except that there is no mesh shielding. The center is the glass core through which the light propagates. In the multimode optical fiber, the diameter of the core is 50 μm to 65 μm, which is approximately equal to the thickness of human hair. The diameter of the single-mode optical fiber core is 8-10 μm. The core is surrounded by a glass envelope having a lower refractive index than the core to retain the optical fiber within the core. Further on the outside is a thin plastic outer sleeve to protect the envelope.

The LC type optical fiber jumper is a connector for connecting an SFP module and is manufactured by adopting a modular jack (RJ) door lock mechanism with convenient operation. The router is commonly used, the joint damage of the existing LC type optical fiber jumper easily affects the jumper, if a plurality of groups of joints are adopted, the weight and the practicability of the cable are increased, and the quality of the cable is seriously affected.

Disclosure of Invention

The utility model aims at overcoming the defect that prior art exists, provide a simple structure's a single tube duplex core LC wire jumper subassembly.

Realize the utility model discloses the technical scheme of purpose is: a single-tube double-core LC jumper assembly is provided with a pipe sleeve, wherein the pipe sleeve is of a hollow structure, a first fiber core and a second fiber core are tightly attached to the inner cavity of the pipe sleeve, and an LC jumper interface is arranged at the end part of the first fiber core.

In the single-tube double-core LC jumper assembly according to the above technical solution, the end of the second optical fiber has a second LC jumper interface.

According to the single-tube double-core LC jumper assembly in the technical scheme, the first fiber core and the second fiber core penetrate through the main optical fiber converter at the tail end of the pipe sleeve.

According to the single-tube double-core LC jumper assembly in the technical scheme, the two ends of the pipe sleeve are the same in structure and are symmetrically distributed.
