A flexible optical fiber ribbon, optical cable and method of making the same

Abstract

The application belongs to the field of flexible optical fiber ribbons, and specifically discloses a flexible optical fiber ribbon, an optical cable and a preparation method thereof. The flexible optical fiber ribbon comprises a plurality of optical fibers arranged side by side in a direction perpendicular to the axial direction of the optical fibers, each optical fiber is provided with an adhesive surface for ribbon bonding on the optical fiber coating, and the adhesive surface is a plane; and ribbon bonding resin is arranged between adjacent optical fibers and used for combining the plurality of optical fibers into a whole, comprising a plurality of unit resins coated at different positions between the adhesive surfaces of adjacent optical fibers, adjacent unit resins are spaced apart in the axial direction of the optical fibers and in the transverse direction of the combined arrangement thereof, only one unit resin is distributed in the same circumferential direction of a single optical fiber, and the radian spanned by one unit resin is less than 120°. The optical fiber in the application can comprise a hollow optical fiber and / or a solid core optical fiber, and the solid core optical fiber can be G.652D, G.654E, G.655, G.657A or the like. The optical fiber ribbon of the application can balance flexibility and bonding firmness.
