ABSTRACT:
An optical waveguide hose includes a hollow tubular cladding, a fluid core in the cladding, the fluid having a higher index of refraction than the cladding, and sealing plugs mated with opposite end openings of the cladding. In one form, the core fluid is filled in the cladding under positive pressure. In another form, a sheath of a gas barrier material encloses the outer periphery of the cladding. The pressurized fluid core or the gas barrier sheath prevents air from penetrating into the core, allowing the hose to maintain its light transmission function.
