Abstract

The invention discloses an optical cable enhancing belt, and a preparation method therefor. The optical cable enhancing belt is made of fiber and resin, wherein the thickness of the optical cable enhancing belt is from 0.3 mm to 1 mm, and the width of the optical cable enhancing belt is from 5 mm to 20 mm. The preparation method comprises the following steps: a plurality of fibers are combined into one combined fiber through a backing-off frame and a guide wheel, and then the combined fiber enters into a resin tank; the fiber is immersed into the resin, and then the adhesive residual resin is removed through a fixed die; and finally the fiber is solidified into a finished product, and is rolled. The belt is advantageous in that the belt enables the fibers of an optical fiber to be wrapped therein, thereby achieving direct enhancement and enabling the optical fiber to have certain stiffness and functions of resistance to pressure, impact, water, rates and ants. Meanwhile, if high polymer material fibers are added, the optical fiber can be enabled to have the above excellent performances and to be better in toughness and stretch resistance.

Description

technical field [0001] The invention belongs to the field of communication optical cables, in particular to an optical cable reinforcement tape and a preparation method thereof. Background technique [0002] At present, optical cables generally use a non-metallic reinforcing rod with a round rod structure. The round rod-shaped reinforcing rod is arranged side by side with the optical fiber and other optical cable components in the outer protective layer of the optical cable. When the optical cable is wired, it is generally necessary to install a protective sleeve outside the optical cable. To the role of support and protection to prevent damage to the optical fiber in the cable. It brings more tedious procedures to the processing of optical cables, and the optical cables have poor water resistance, anti-expansion, and anti-rat performance. Contents of the invention [0003] The object of the present invention is to provide a fiber optic cable reinforcement tape and a prep...
