摘要： PROBLEM TO BE SOLVED: To obtain a coated optical fiber ribbon that facilitates peeling of multiply coated layers successively stepwise from the outside.
SOLUTION: The coated optical fiber ribbon 10 is formed by arraying coated optical fiber ribbons 20, coating them all together, and repeating this arraying and coating process for a prescribed number of times. Since the tensile strength of the outer coating layers 22a is made smaller than that of the inner coating layers 21a, peeling successively from the outer coating layers 22a is made possible by rubbing the coated optical fiber ribbon 10 with a brush, enabling the ribbon to be separated stepwise into a prescribed number of coated fibers. In addition, by making the tensile strength of a resin used for the outermost layer 22a to be ≥0.5 kgf/mm
2 and that of a resin for the innermost layer 20a to be ≤8.0 kgf/mm
2 , the separation characteristics can be improved.
