Abstract

The article describes a fiber transmission system for use with communication networks such as a Fiber Data Distribution Interface (FDDI) system. The system, shown in the drawing, includes a thin aluminum sheath such as used for hard-line coax import cables. The plurality of aluminum tubes are fitted inside of the almunim sheath, and glass fibers are blown in the aluminum tube at a later date. The aluminum tube could be used with or without an extruded outer layer of inorganic polymer or wrapped with silicon, etc. The inner tubes, also of aluminum, are microducts for allowing glass fiber to be blown in at some time after the structure is fitted in the building.

Plenum Blown Fiber Duct System

      The article describes a fiber transmission system for use with
communication networks such as a Fiber Data Distribution Interface
(FDDI) system.  The system, shown in the drawing, includes a thin
aluminum sheath such as used for hard-line coax import cables.  The
plurality of aluminum tubes are fitted inside of the almunim sheath,
and glass fibers are blown in the aluminum tube at a later date.  The
aluminum tube could be used with or without an extruded outer layer
of inorganic polymer or wrapped with silicon, etc.  The inner tubes,
also of aluminum, are microducts for allowing glass fiber to be blown
in at some time after the structure is fitted in the building.
