Problems solved by technology

However, most of the existing FTTH optical cables have low mechanical performance requirements, and few FTTH optical cables have the characteristics of high tensile strength, torsion resistance, and sheath shedding. The sleeve and the reinforcing element are disengaged and cannot be restored to the original position, the optical fiber is easily twisted, and the sheath layer is easy to crack, resulting in failure of the optical cable

Abstract

The invention discloses a novel FTTH optical fiber cable and a production process thereof. The novel FTTH optical fiber cable has the advantages of high adhesion between a reinforcing element and a sheath, torsion resistance, crack resistance, sheath tension resistance and stable structure, and is suitable for optical fiber cables in various complicated installation environments. The novel FTTH optical fiber cable of the invention is composed of a sheath layer, an optical fiber and a reinforcing element; the novel FTTH optical fiber cable comprises an indoor FTTH optical cable and an indoor and outdoor dual-purpose FTTH optical cable. The indoor FTTH optical cable only comprises a main component, and the indoor and outdoor dual-purpose FTTH optical cable comprises a main component and an auxiliary component integrally with the main component. The main component comprises a reinforcing element, a reinforcing element coating layer, a sheath layer and an optical fiber coated with the sheath layer, which are sequentially arranged from the inside to the outside; and the auxiliary component comprises a reinforcing element, a reinforcing element coating layer and a sheath layer arranged sequentially from the inside to the outside.

Description

technical field [0001] The invention relates to the technical field of FTTH optical cable production, in particular to a novel FTTH optical cable and a production process thereof. Background technique [0002] The FTTH optical cable is usually made of one or more isolated optical fibers, strengthening elements and the sheath (protection) layer of the optical cable, and the optical fiber is used as the transmission medium between the central office and the user. FTTH optical cables are widely used to install and connect optical network units (ONU) to residential users or enterprise users. With the continuous development of technology and society, FTTH optical cables are widely used in different environments, and the places that need to use FTTH optical cables are becoming more and more complicated. ,diversification. However, most of the existing FTTH optical cables have low mechanical performance requirements, and few FTTH optical cables have the characteristics of high tens...
