| 摘要 |
The inventive optical fiber ribbon includes a plurality of optical fibers horizontally arranged, upper and lower coating layers coated in upper and lower portions of the optical fibers, and side surface coating layers coated on outer surfaces of farthest optical fibers from the center of the optical fibers and having a thickness thinner than that of the upper and lower coating layers. A device of manufacturing an optical fiber ribbon is provided and includes a dye body, and a dye hole penetrating the dye body and having a cross section of a rectangular shape, characterized in that the dye hole has a height H expressed by an equation reading H=D+(0.05~0.2 mm) (wherein D represents an external diameter of said optical fiber), and a width W expressed by an equation reading W=DxN+(0~0.1 mm) (wherein N represents a number of cores of the optical fiber).
