ABSTRACT:
An optical waveguide tube has a transparent core received in a cladding having a lower refractive index than the core. The entire cladding or an inner layer of the cladding fitting on the core is formed of a fluororubber which has been vulcanized by radical crosslinking. The vulcanized fluororubber has a residual halogen atom content of up to 80 ppm. A trapping agent surrounds the cladding for trapping coloring substances. The optical tube maintains satisfactory optical transmission capability over a long time while the core is not colored.
