Air-distribution fiber-ribbon-introduced cable

Abstract

The invention provides an air-distribution fiber-ribbon-introduced cable comprising a first bearing unit, a second bearing unit, and fibers. A plurality of fibers are arranged between the first bearing unit and the second bearing unit. A first isolation part is arranged between the fibers and the first bearing unit; and a second isolation part is arranged between the fibers and the second bearing unit. The first isolation part and the second isolation part are in contact with the fibers. The first isolation part is separated from the first bearing unit; and the second isolation part is separated from the second bearing unit. Besides, a main protection layer coats the first bearing unit, the second bearing unit, the fibers, the first isolation part, and the second isolation part; and a first stripping positioning opening group and a second stripping positioning opening group that are arranged in pairs are arranged at positions corresponding to the first isolation part and the second isolation part outside the main protection layer. Therefore, the overall tensile strength of the cable is enhanced by 40%, so that the cable can be supported in an overhead manner effectively, the damage of the cable is reduced, and the cable erection cost is lowered. On the basis of the isolation part design, protection layer stripping of the cable is carried out conveniently.

Description

technical field [0001] The invention belongs to the field of optical cables, in particular to an aerial distribution lead-in optical fiber ribbon optical cable. Background technique [0002] The optical cable is composed of multiple optical fibers and the outer protective layer for optical fiber protection. It has the superior performance of high safety and high reliability in signal transmission. The optical cable is usually laid overhead before installation and access. In the prior art, when the protective layer of the optical cable laid overhead is stripped, due to the different strength of the construction personnel and the different performance and reliability of the stripper, the protective layer cannot be quickly stripped, and sometimes the optical fiber at the stripped place will be damaged; the existing When the optical cable is laid overhead, because the optical cable itself lacks the main support structure, it mainly relies on the optical fiber and the thin steel ...

[0002] The optical cable is composed of multiple optical fibers and the outer protective layer for optical fiber protection. It has the superior performance of high safety and high reliability in signal transmission. The optical cable is usually laid overhead before installation and access. In the prior art, when the protective layer of the optical cable laid overhead is stripped, due to the different strength of the construction personnel and the different performance and reliability of the stripper, the protective layer cannot be quickly stripped, and sometimes the optical fiber at the stripped place will be damaged; the existing When the optical cable is laid overhead, because the optical cable itself lacks the main support structure, it mainly relies on the optical fiber and the thin steel wire close to the optical fiber to provide support. Such an optical cable lacks a certain structural strength, which is easy to cause the overall damage of the optical cable.
