Abstract
Disclosed herein is an optical fiber cable produced by pumping a two-liquid mixing and curing-type polyurethane resin which has the specified values in a tensile break strength, a breaking extension, a creep characteristics and the compression modulus of elasticity, in voids surrounding the optical fibers and those surrounding tension members of the cable.
Claims7
A submersible optical fiber cable produced by filling the voids surrounding the optical fibers and the surrounding tension members of the cable with a two-liquid mixing and curing polyurethane resin which has a tensile breaking strength of higher than 0.30 kg/cm.sup.2, a breaking extension of larger than 200%, creep characteristics (.epsilon..sub.t /.epsilon..sub.0) obtained by calculation in the stress-relaxation test of less 2.8 within 60 second of the determination time and a compression modulus of elasticity of less than 80 kg/cm.sup.2.
