A prefabricated tight-buffered fiber-core butterfly drop cable and its realization method

Abstract

The invention relates to an end-prefabricated tightened fiber core butterfly guiding-in optical cable and an implementation method of the end-prefabricated tightened fiber core butterfly guiding-in optical cable, and belongs to the technical field of optical cable connection. The end-prefabricated tightened fiber core butterfly guiding-in optical cable comprises a ceramic inserting core positioned at the front end of an optical cable quickening device, connector parts and components and a tightened fiber core butterfly guiding-in optical cable connected with the ceramic inserting core, wherein the tightened fiber core butterfly guiding-in optical cable comprises an outer sheath, non-metallic reinforcement members symmetrically arranged inside the outer sheath, and a coloring optical cable arranged at the center of the outer sheath; and a protective sleeve is arranged outside the coloring optical cable through sleeve connection. The end-prefabricated tightened fiber core butterfly guiding-in optical cable disclosed by the invention is reasonable in design, simple in structure and good in tensile effect.

Description

technical field [0001] The invention belongs to the technical field of optical fiber splicing, and in particular relates to a prefabricated tight-buffered fiber-core butterfly lead-in optical cable and a realization method thereof. Background technique [0002] In the development of the FTTH project, the butterfly cable is used as the transmission medium between the central office and the user. In the process of use, it must be considered to connect the optical fiber or optical cable to each other in a method that is convenient for construction, easy to operate, and low loss. Generally, movable Connectors can be used to achieve selective intermatching between active connectors to achieve rapid connection of optical links between homes and corridors. [0003] Prefabricated-end butterfly lead-in cable, referred to as "skin jumper", is a reusable passive device used to connect optical fibers or butterfly lead-in cables to form a continuous optical path, and has been used in opt...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: 1. Since the prestress generated between the outer sheath and the fiber core is not considered in the design of the ordinary butterfly-shaped lead-in cable, the outer sheath is pulled by the internal stress during the production process, and the fiber core is also pulled. It is easy to cause the fiber core to break

2. In the process of use, when the prefabricated butterfly-shaped lead-in optical cable is operated, the ferrule retracts during the retraction process because the outer sheath tightly wraps the fiber core, and the short-distance space of the fiber core section after removing the outer sheath cannot be retracted. causing bending and breaking

3. Ordinary butterfly-shaped lead-in cable is an "8"-shaped butterfly-shaped lead-in cable that protects the fiber core through the coating layer, but when the outer sheath is stripped, the coating layer at the outer sheath stripped by the special leather wire stripping pliers There is damage, which will not only affect the optical performance of cold connectors, quick connectors and leather jumpers, but also cause a lot of waste, which increases the cost of use
