Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, and specifically relates to a waterproof optical fiber jumper wire. Background Art

[0002] Optical fiber is the abbreviation of optical waveguide fiber, which is a fiber made of glass or plastic and can be used as an optical conduction tool. The transmission principle is "total internal reflection of light". Optical fiber jumper wires are used as jump wires from devices to optical fiber wiring links. They have a relatively thick protective layer and are generally used for connections between optical terminal machines and terminal boxes. They are applied in some fields such as optical fiber communication systems, optical fiber access networks, optical fiber data transmission, and local area networks. Optical fiber jumper wires are also called optical fiber connectors, that is, the optical fiber connectors for accessing optical modules. There are also many types and they cannot be used interchangeably with each other, such as FC type optical fiber jumper wires, SC type optical fiber jumper wires, ST type optical fiber jumper wires, and LC type optical fiber jumper wires.

[0003] During the use of communication equipment, in order to ensure the normal transmission of data and signals, optical fiber jumper wires are needed. The patent publication number is CN220829617U.

An OPGW optical fiber filling paste layer is filled outside the fiber wrapping layer. An FRP strengthening core layer is wrapped inside the OPGW optical fiber filling paste layer. The beneficial effects are as follows: Through the design of the FRP strengthening core layer, the tensile strength of the optical fiber jumper wire is increased, and the phenomenon that the internal optical fiber breaks due to excessive bending and winding can be effectively avoided. At the same time, through the design of the OPGW optical fiber filling paste layer, the optical fiber jumper wire will not generate substances such as mildew due to dust and other impurities during use, which not only protects the internal structure of the optical fiber jumper wire, but also improves the transmission efficiency of the optical fiber jumper wire.
