PURPOSE: To easily and stably separate a material which constitutes an optical cable and is used in combination in the case of recycling of the optical fiber cable which is made unnecessary by inserting cord-shaped members along the boundary of the material.

CONSTITUTION: A tension member 11 as the constituting member for the optical fiber cable consists of steel stranded wires 12 in tight contact with each other and a resin layer 13 and is integrally provided with the cord 14 for tearing the material along the boundary thereof. Then, shearing force is applied to the resin layer 13 consisting of a polyethylene, etc., covering the circumference of the steel stranded wires 12 by pulling one end of the cord 14 for tearing and applying the tension on the resin layer as shown in Fig. Consequently, the easy sepn. of the steel stranded wires 12 and the resin layer 13 is possible and the easy and safe sepn. of the material constituting the optical cable is possible in the case of recycling of the unnecessary optical fiber cable.
