Bow-type drop cable with physical rat-proof function and manufacturing method of drop cable

Abstract

The invention provides a bow-type drop cable with physical rat-proof function and a manufacturing method of the drop cable. The bow-type drop cable comprises a bow-type cable, an optical fiber and an optical fiber armor, wherein the bow-type cable is provided with a suspension wire reinforcing part, a first reinforcing part and a second reinforcing part which are fixed in an outer sheath through injection molding, V-shaped tearing ports are formed in two sides of the outer sheath and located between the first reinforcing part and the second reinforcing part, the optical fiber is arranged between the V-shaped tearing ports on the two sides, and the periphery of the optical fiber is wrapped with the optical fiber armor. The manufacturing method comprises the steps as follows: molding of the optical fiber with the optical fiber armor and extrusion molding of the outer sheath. The problems of poor physical rat-proof and mechanical performance of the bow-type drop cable are solved, the periphery of the optical fiber is wrapped with a stainless steel pipe, the outer sheath can still have the physical rat-proof function after being bitten, and the tensile property and lateral pressure resistance of the bow-type drop cable are improved.

Description

technical field [0001] The invention relates to the technical field of butterfly-shaped lead-in optical cables, in particular to a physically rat-proof butterfly-type lead-in optical cable and a manufacturing method thereof. Background technique [0002] Butterfly-type lead-in cables have poor rodent-proof performance. Butterfly-type lead-in cables are routed in densely populated areas, which are also areas where rodents gather. Rodents have the habit of biting objects to keep their teeth sharp, and are prone to rodents such as mice. The biting of the fiber optic cable brings a lot of trouble to the design and maintenance of the optical cable. At present, a large number of butterfly optical cables are used for light-to-the-home. There are two types of structures: self-supporting and non-self-supporting. Vulnerable. Contents of the invention [0003] The purpose of the present invention is to aim at the above-mentioned problem that existing technology exists, provides a k...
