Abstract
An optical fiber cable has an optical fiber core wire and a tension member. The tension member is formed of a glass fiber reinforced resin linear material with glass fibers and a matrix resin, and satisfies the following requirements: (1) (EfVf+EmVm)d2≧8.3/n wherein Ef represents the modulus of elasticity of glass fibers, GPa; Vf represents the content of glass fibers, %/100; Em represents the modulus of elasticity of matrix resin, GPa; Vm represents the content of matrix resin, %/100; d represents the diameter of tension member, mm; and n represents the number of tension members used in optical fiber cable; (2) (Ef/Em)≧22; (3) Vf=0.6 to 0.88; and (4) an elongation at break of glass fibers of not less than 5% and an elongation at break of matrix resin of not less than 5%.
