Abstract:
1. An optical cable comprising: a coated optical fiber having a bared fiber mainly comprised of silica glass, and a coating layer provided on an outer periphery of said bared fiber and comprised of an ultraviolet curing resin, said coating layer including; a first coating with a Young's modulus of 200 MPa or more; a second coating provided between said bared fiber and said first coating, said second coating having a Young's modulus of 0.5 to 2 MPa; a colored layer provided on the outer periphery of said coated optical fiber, said colored layer having a rupture elongation of 10% or more; and a protective layer provided on an outer periphery of said colored layer, said protective layer being comprised of an ultraviolet curing resin with a Young's modulus of 50 to 300 MPa; and a cable jacket provided on an outer periphery of said coated optical fiber and having a minimum thickness of 0.7 mm or more, said cable jacket, which is comprised of a non-halogen-containing thermoplastic resin, having a Young's modulus equal to or greater than that of said first coating, the Young's modulus being 500 MPa or more but 1500 MPa or less.
