This invention relates to fiber optics and more particularly to a method and apparatus for optical fiber transmission in a utility conduit containing a hostile fluid. It is an object of this invention to provide a simple and economical method of introducing an optical fiber into a utility conduit containing a hostile fluid the practice of which method will not degrade the optical or mechanical performance of the fiber. It is a further object of this invention to provide a method of introducing an optical fiber into a hostile fluid-carrying utility conduit which may comprise a part of an existing utility distribution system for water, gas or oil and the like. It is a still further object of this invention to provide optical fiber transmission apparatus which utilizes existing piping systems and other conduits carrying hostile fluids and which does not require expensive non-flexible shielding arrangements or armored cable for the optical fiber.
