Abstract
An optical cable has tensile elements and supporting elements embedded in an extruded outside cladding. The tensile elements are hauled-off from a supply reel and introduced into an extruder head serving to manufacture the outside cladding. The supporting elements are manufactured in a coextrusion with the outside cladding by appropriate channels formed in the extruder head.
Claims16
In an optical cable having an outside cladding surrounding waveguides with embedded tensile elements, the improvements comprising an inside layer being surrounded by the outside cladding to extend generally longitudinally therein said inside layer being a supporting element, the tensile elements being fashioned skein-like being embedded in the outside cladding.
In an optical cable having an outside cladding with tensile elements surrounding waveguides, the improvement comprising the cladding including at least one supporting element of an extruded material and the tensile elements being generally longitudinally extending skein-like elements embedded in the outside cladding.
An apparatus for extruding an outside cladding with tensile elements and supporting elements on internal waveguides, said apparatus comprising an extruder head being provided with an interior passage through which the light waveguides are supplied to a discharge opening, said extruder head having an annular gap adjacent said opening, conduits for transporting tensile elements to said annular gap, channels being formed for guiding the material for the supporting elements to said gap and a passage for transporting the cladding material to said gap.
