Abstract

An optical cable comprises a coated optical fiber having an optical fiber which includes a core made of glass and a cladding surrounding the core and a jacket made of a thermoplastic resin. The jacket is directly covering the coated optical fiber while in close contact therewith. In the optical cable, the optical fiber has the highest modulus of elasticity in materials constituting the optical cable, a glass diameter of the optical fiber is at least 30 μm but not more than 200 μm while being 5% or less of a cable diameter of the optical cable, and a distortion occurring in the optical fiber when bending the optical cable by 180° is 6% or less.
