Abstract
A coated plastic cladding optical fiber and an optical fiber cable, in which a transmission loss caused when this coated fiber or this fiber cable is bent in a small radius is small, and which can be used sufficiently as a USB cable or a HDMI cable in a high speed transmission, are provided.The coated plastic cladding optical fiber 1 has a cladding layer 3 that is formed on an outer periphery of a core glass 2 made of a quartz glass and formed of a polymer resin whose refractive index is lower than core glass, and a resin coating layer 5 that is formed on an outer periphery of the cladding layer 3 and is formed of a thermosetting resin. Then, a diameter of the core glass 2 is set to 50 to 100 μm, and a relative index difference of the core glass 2 to the cladding layer 3 is set to 3.7% or more.
