Abstract
PURPOSE: To eliminate crossing of optical fibers by aligning the twisting direction and twisting pitch of the optical fibers of the respective layers of the multilayer optical cable.
CONSTITUTION: The optical cable is constituted by a tension member 1, multilayer optical fibers 6..., sheath 3, etc. If the tiwsting direction and twisting pitch of the optical fibers 6... forming the respective layer of this cable are made identical, the fibers 6... between the layers do not mutually cross and contact. Hence, microbending owing to distorsions produced by crossing is eliminated and the degradation in the characteristics of the fibers is prevented.
