Integrated optical communication cable

Abstract

The invention relates to an integrated communication optical cable, which comprises a cable core, a central sleeve and an oversheath in turn from an inner layer to an outer layer, wherein the cable core comprises a plurality of minisize optical fiber units which are intertwisted or arranged in parallel and fiber pastes filled between the minisize fiber units and the central sleeve, and each minisize fiber unit comprises a micro sleeve, an optical fiber arranged in the micro sleeve, and a fiber paste filled between the micro sleeve and the optical fiber. By using the characteristics of the structures of the minisize fiber units and universal central tube bundle fibers, the minisize fiber units are arranged in the central sleeve, thus not only the optical fibers are under dual mechanical protections, but also corresponding minisize optical fiber units are diverged from optical cables and are placed in a conduit by only stripping off the oversheath and the central sleeve of the optical cable in occasions that the minisize optical fibers are needed specially. The integrated communication optical cable is adaptable to various laying modes such as overhead laying, conduit laying, direct-buried laying and the like.

Description

technical field [0001] The invention relates to a communication optical cable, in particular to an outdoor communication optical cable. Background technique [0002] With the development of optical fiber communication technology and industry, the structure of outdoor optical cables for communication has become increasingly mature and has formed a number of series of products. In terms of optical cable laying technology, in recent years, air-delivered optical cable technology has also been developed. The air-fed cable system is a cable laying technology that uses compressed air (about 10kg / cm2) from an air compressor to blow the fiber unit into the installed hollow cable duct through the blowing head. In the actual laying, the set number of optical fibers is first made into an optical fiber micro-sleeve unit, and after being cabled, a simple and light optical cable structure is formed, and then sent into the preset pipe by blowing air. Air-delivery cable technology has its ...

AI Technical Summary

Problems solved by technology

But its laying method is relatively simple, and the construction is extremely inconvenient

In particular, this kind of air-delivered optical cable cannot adapt to laying methods such as overhead and direct burial, and it is impossible to carry out branching construction of the optical cable midway, which greatly limits the application occasions of air-delivered optical cable
