もの。[Claims for Utility Model Registration] 1. A spacer for an optical fiber cable in which a tensile strength member is closely disposed inside the center of a space forming body having a plurality of groove spaces at the periphery for loosely accommodating optical fibers,
A spacer for an optical fiber cable, characterized in that the tensile strength member is composed of at least one tensile strength member having a high modulus of elasticity and a negative coefficient of thermal expansion. 2 Utility Model Registration In the optical fiber cable spacer according to claim 1, the sum of the values of (Young's modulus x cross-sectional area x coefficient of thermal expansion) of both the tensile strength body and the space forming body is calculated as (Young's modulus of both). The absolute value of the value divided by the sum of the values (ratio x cross-sectional area) is set to be 10-6 or less. 3 Utility Model Registration Scope of Claims 1. The spacer for optical fiber cables according to claim 1, wherein the tensile strength body is made of a wire made of a polymeric material having a high modulus of elasticity and a negative coefficient of thermal expansion, and having iron as its main component. It is formed by closely adhering wire rods of metallic materials.
