Abstract

PURPOSE:To pull out the overall length of the optical fiber from the cable end by a desired length, by constituting the core material of the cable by joining unit core materials and by making it possible to pull out unit core materials from the cable end. CONSTITUTION:Core material 1, optical fiber 2, protection layer 3, unit core material 11, tension member 12, coating material 13, and undercut 14 are provided. Core material 1 has the discontinuous structure in the longitudinal direction and is pulled out by several (m) by pulling core material 1 from the cutting end of the cable. Therefore, undercuts 14 are provided in core material 1 at every several (m), and core material 1 is separated by pulling it. Thus, if core material 1 is pulled out from the cable end by several (m), the overall length of unit core material 11 is taken out from optical fiber 2 twisted on core material 1 which is pulled out.
