Abstract
PURPOSE: To reduce the change of loss against external force by changing the hardness of the buffer layer of the optical fiber core provided between optical fiber strand and the protecting covering on the outer layer in its radial direction and forming the optical fiber core.
CONSTITUTION: In forming the optical fiber core by providing a buffer layer 4' around an optical fiber strand 1 and further laminating a protection covering 3 such as plastics or the like on the outer side thereof, the hardness of the buffer layer 4' is changed as it goes away in the diametral direction from the axial center thereby forming the buffer layer (in the figure (b), 5, 6, 7 denote the hardnesses of the optical fiber strand, protection covering and buffer layer respectively).
