Adhesive heat shrink tube cold joint twin-core rubber-covered wire optical cable jumper wire

Abstract

The invention discloses an adhesive heat shrink tube cold joint twin-core rubber-covered wire optical cable jumper wire comprising a twin-core rubber-covered wire optical cable, an adhesive heat shrink tube, an optical cable hollow tube and an optical fiber flexible connector. The twin-core rubber-covered wire optical cable comprises a butterfly external sheath and two optical fibers which are arranged at the center of the butterfly external sheath. The two sides of the two optical fibers are provided with reinforcing cores along the length direction. The external sheath of one end of the twin-core rubber-covered wire optical cable is stripped and then the two optical fibers are exposed to penetrate through the optical cable hollow tube to be connected with the optical fiber flexible connector. A part of the adhesive heat shrink tube sleeves the non-stripped external sheath, and another part sleeves the optical cable hollow tube. The joint efficiency of the prefabricated end and the optical fiber flexible connector at the rubber-covered wire optical cable site can be greatly enhanced by the adhesive heat shrink tube cold joint twin-core rubber-covered wire optical cable, and the problem of respective joint end formation of the current twin-core optical cable can also be solved so that instant and efficient starting and maintenance of FTTH (Fiber To The Home) can be realized.

Description

technical field [0001] The invention relates to a leather-wire optical cable, in particular to a double-core leather-wire optical cable jumper with glued heat-shrinkable tubes for cold splicing. Background technique [0002] FTTH (fiber-to-the-home) leads broadband access, and the network is deeply affecting our lives. For fiber-to-the-home network deployment, the butterfly-shaped lead-in leather cable is an FTTH (fiber-to-the-home) indoor drop-in cable, and the double-core leather cable is a 2-core leather cable, which includes 2 optical fibers, 2 strengthening cores and a sheath , the sheath is wrapped around the optical fiber. The cable has a novel structure and has been recognized as the best FTTH (fiber-to-the-home) access indoor optical fiber cable. In the implementation of fiber-to-the-home transformation, although this type of optical cable has a dual-core structure, generally only one core is used, and the other core is used as a backup. When directly connected to ...

Problems solved by technology

In the implementation of fiber-to-the-home transformation, although this type of optical cable has a dual-core structure, generally only one core is used, and the other core is used as a backup. When directly connected to the user end, the optical fiber can be fully protected by the outer sheath of the optical cable. Due to changes in business volume and scope of use, the client needs to use two cores at the same time. When using them, the two cores must be separated and used separately. In the process, the 0.125mm optical fiber will be exposed and easily damaged, which increases the difficulty and risk of construction.

At present, it is very difficult to branch the double-core leather cable and to splice or terminate the two cores at the same time.
