Abstract
An optical waveguide hose includes a hollow tubular cladding made of a material having rubber elasticity at the service temperature of -50.degree. to 150.degree. C. and having a lower creep. The cladding is filled with a core fluid having a higher index of refraction than the cladding and closed with sealing plugs at opposed open ends. The hose is improved in flexibility and handling, prevents gas penetration into the core fluid, maintains transparency at widely varying temperature over a long time, and is lightweight and inexpensive.
