Abstract

The invention discloses a skeleton fiber bundle optical cable with semicircular skeleton grooves, and relates to an optical cable applied to a communication network. The skeleton fiber bundle optical cable comprises a skeleton with a cylindrical hollow structure. A central reinforcement part is arranged in the center of the skeleton. A layer of outer sheath is extruded on the outer wall of the skeleton. The skeleton grooves are uniformly distributed along a circumferential direction on the inner wall of the skeleton, and have semicircular cross sections. A plurality of fiber bundles with circular cross sections are distributed in each semicircular skeleton groove. The fiber bundles with the circular cross sections are arranged in the skeleton grooves with the semicircular cross sections, so that the problems of great diameter, low yield, high fiber attenuation of fiber ribbons, and the like of an ordinary skeleton fiber ribbon optical cable are solved.

Description

technical field [0001] The invention relates to an optical cable suitable for a communication network, in particular to a framework type optical fiber bundle optical cable with a semicircular framework groove. Background technique [0002] The existing skeleton optical fiber ribbon cable has excellent structural lateral pressure, and the optical fiber ribbon can be taken out directly after the skeleton structure is stripped, which is convenient for branching and laying. However, since the optical fiber ribbon is ribbon-shaped and has a relatively large width, the diameter of the skeleton-type optical fiber ribbon cable produced is relatively large, which is not conducive to the full utilization of pipeline resources. Moreover, the special shape of the optical fiber ribbon also causes the optical fiber ribbon in the optical cable to often scatter during the production process, so that the entire optical cable is scrapped, resulting in a low yield rate, which seriously affects...
