Flexible optical fiber cable

Abstract

The invention discloses a flexible optical fiber cable which comprises a cable core, at least one optical fiber layer located outside the cable core and a protective layer located outside the optical fiber layer; the optical fiber layer is formed by spirally winding a wire outside the cable core, and the wire is an optical fiber or comprises an optical fiber. On one hand, the bending resistance of the optical fiber can be improved, the optical fiber is not easy to break when being bent; and on the other hand, the winding distance can be regulated, and the optical power loss of the optical fiber is ensured to be minimum.

Problems solved by technology

The flexible optical fiber in the prior art usually includes an optical fiber and a sheath outside the optical fiber. The bending radius (also called bending radius) of the flexible optical fiber is the bending radius of the optical fiber. It is generally recommended to be about 30 mm. However, in In practical applications, the bending radius of the flexible optical fiber cable by the user or construction personnel is often smaller than the recommended value, resulting in the phenomenon that the optical fiber is often broken

Therefore, the flexible optical fiber wires of the prior art have poor bending resistance

In order to solve the problem that the optical fiber is not resistant to bending, some optical fibers are braided, but the braided optical fiber has a too small braiding pitch and is difficult to adjust, resulting in a large loss of optical power
