Problems solved by technology

[0004] The traditional air-blown optical fiber unit generally only has a sheath protective layer, which is not rigid enough, and the tensile strength and lateral pressure resistance of the optical cable are also poor. During the air-blown laying process, it is easy to cause microcables Bending occurs, resulting in fiber breakage and damage to the optical cable

Abstract

The invention discloses an air-blowing micro-cable and a preparation method thereof; the air-blowing micro-cable is provided with an outer sheath and a cable core arranged in the outer sheath; the cable core comprises three optical fiber units and three reinforcing units, the optical fiber units and the reinforcing units are arranged in a stranded mode, the optical fiber units and the reinforcingunits are stranded in a one-way S mode, and the periphery of the cable core is coated with a reinforcing layer. The invention provides the air-blowing micro cable. Compared with a traditional air-blowing optical fiber unit, the optical fiber unit cured through resin and the reinforcing unit are adopted for twisting the cable core, the rigidity of the optical cable is effectively improved, the reinforcing layer is coated, the tensile strength of the air-blowing micro-cable is further improved, and the bending risk of the air-blowing micro-cable is reduced; the air-blowing micro-cable is suitable for rapid long-distance air-blowing laying, and the construction laying efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of microcable design, in particular to an air-blown microcable and a preparation method thereof. Background technique [0002] This section is intended to provide a background or context to the implementations of the application that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Air-blown micro-cables can effectively improve the utilization rate of pipeline resources and have high deployment efficiency. They are widely used in access networks, metropolitan area networks, and communication backbone networks. As a mature optical cable network laying technology, the air-blown micro-tube and micro-cable technology can effectively solve the problems of high investment cost of one-time performance and shortage of communication pipeline resources for operators. have large-scale applications. In the process of optical fiber bro...
