Problems solved by technology

[0004] However, when encountering many occasions with short spans and fewer optical fibers, the "8" cable of the traditional structure is wasteful. In order to save costs, multi-strand steel wires are usually changed to single-strand steel wires. The sheath structure is directly extruded outside the casing, and the optical cable with this structure can withstand a long-term tensile force of 1000N

Embodiment Construction

[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0020] Please refer to figure 1 , the miniature 8-shaped optical cable of the present invention comprises a single-strand self-supporting steel wire 10, one or more optical fibers 20, a loose tube 30 covering the optical fiber 20, an aramid fiber layer 40 covering the loose tube 30 and the The single-strand self-supporting steel wire 10 is wrapped with the sheath 50 wrapped by the aramid fiber layer 40 .

[0021] In this embodiment, an aramid fiber layer 40 is added outside the loose tube 30 of the existing miniature figure-of-eight optical cable, and the aramid fiber layer 40 is used as an added support unit, without increasing the outer diameter of the original optical fiber cable and without increasing the cost , so th...

Abstract

The invention discloses a mini-sized 8-shaped optical cable. The mini-sized 8-shaped optical cable comprises single-strand self-supporting steel wires, optical fibers, a loose casing pipe which wraps the optical fibers, an aramid fiber layer which wraps the loose casing pipe and a protective sleeve which wraps the single-strand self-supporting steel wires and the aramid fiber layer. According to the mini-sized 8-shaped optical cable, the aramid fiber layer is added to the existing mini-sized 8-shaped optical cable which is formed by the single-strand self-supporting steel wires so that the short-term affordable tensile force and the long-term affordable tensile force of the mini-sized 8-shaped optical cable are greatly increased with smallest invest costs.

Description

technical field [0001] The invention relates to an optical cable, in particular to a miniature figure-eight optical cable. Background technique [0002] An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. [0003] Since the "8" self-supporting optical cable has its own self-supporting steel wire, it can be suspended and wired by fixed hanging wire steel wire during outdoor construction, which makes the wiring easier and is favored by customers. In the prior art, in order to enhance the short-term tensile force of the "8"-shaped self-supporting optical cable, the self-supporting steel wire is usually twisted with multiple strands of steel wire, and the "8"-shaped self-supporting cable with such a structure is adopted. The short-term tensile force of the optical cable can reach 8000N, or even ...
