Problems solved by technology

This structure has high requirements on the manufacturing process and the yarn binding material, and the unsuitable manufacturing process may easily cause the yarn binding material to break, the loose tube to be punctured, the optical fiber to be broken, and the binding body to be loose due to insufficient binding. Seriously affect the yield and quality of optical cables
[0003] There are also some technical solutions that try to improve the structure and materials of optical cables, but on the one hand, they are always unsatisfactory in terms of stability, optical performance, and bending ability of optical cables. On the other hand, the manufacturing process of such optical cables is complicated and difficult to operate. Therefore, it is the current market demand to produce a brand-new optical cable with a simple and easy manufacturing process.

Abstract

The invention relates to a method for manufacturing a filling type cable. The method comprises: coloring is carried out on a fiber; a blank pipe is manufactured at the periphery of the colored fiber, the blank pipe is filled with filling ointment, and then plastic sleeving is completed to form a fiber plastic pipe; the fiber plastic pipe encircles the periphery of a reinforced element in a twisting manner to form a twisting body, an ethylene-vinyl acetate copolymer material coats the periphery of the twisting body to form a cable core; and a sheath protection layer is manufactured at the periphery of the cable core to form a filling type cable. According to the manufacturing method, the process is simple; the generated cable core number is large; the structure is stable; and the anti-side pressure and anti-impact capabilities are high.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication optical cables, in particular to a method for manufacturing an injection-filled optical cable. Background technique [0002] In recent years, with the continuous development of optical fiber network communication in my country, the demand for optical fiber cables is increasing, and the technical requirements for optical cables are also getting higher and higher. Ordinary optical cables usually spend a lot of time and energy on the construction and maintenance of optical cables during operation. Existing optical cables are mainly divided into filled optical cables, fully dry optical cables and semi-dry optical cables, among which filled optical cables and semi-dry optical cables Type optical cables are filled with ointment, which is more time-consuming and laborious in terms of construction connection and subsequent maintenance, and the ointment brings a lot of inconvenience in ...
