<P>PROBLEM TO BE SOLVED: To excellently discriminate an optical fiber element having numerous types in an optical fiber tape core wire in which a plurality of the optical fiber elements are connected in parallel, and also discriminate the optical fiber tape core wire even when the optical fiber element is used as a unit by preventing reduction in discriminability due to aged deterioration and peeling off the taperized fiber. <P>SOLUTION: For every predetermined distance in the longitudinal direction, a marking 4 having different one for each optical fiber element 1 is applied to the surface thereof, and the optical fiber table core wire is covered with a translucent colored layer having the same color for discriminating the optical fiber tape core wire. <P>COPYRIGHT: (C)2012,JPO&INPIT |
