<p>OPTICAL CABLE MANUFACTURE A method and apparatus for manufacture of an optical cable having a plurality of optical fibers surrounded by a protective tube. The fibers are loosely contained within the protective tube which comprises longitudinally extending closely packed tensile filaments embedded in a continuous solidified and rigid carrier material. The carrier material is preferably a polystyrene a polyester or an epoxy based resin. A water blocking medium may fill the protective tube. The protective tube is made by covering the tensile filaments with the carrier material in a flowable state, guiding the coated filaments through a tubular space so as to fill it and causing solidification of the carrier material inside the tubular space. The optical fiber is passed through a tubular guide which defines the inner surface of the tubular space so that the optical fibers lie within the formed protective tube.</p> |
