Abstract: A coextruded innerduct which would include an outer layer of polyethylene, impregnated or filled with a filler material, such as calcium carbonate, talc, microglass beads or strands, or any material which would reduce the contraction and expansion properties of the polyethylene innerduct in relation to the properties of the outer casing, and an inner layer of unfilled polyethylene innerduct which would provide for a smooth surface, to lower the coefficient of friction between itself and the fiber optic cables being pulled therethrough. There is further provided a lubricity agent added to the inner layer, and the innerduct is positioned as part of a multi-cell system when installed for use.

Abstract: An assembly for the coupling of a multi-duct conduit system for sealing the outer and inner ducts of adjacent conduit sections in end to end relationship. There is provided a primary coupling housing which includes preferably a premolded body portion which is insertible into the outer most housing of a ducted system. The body system in the body portion comprises first and second half body portions. Each first and second half body portion is adapted to receive a plurality of ducts into bores in the body housing so that a first plurality of ducts enters and is insertible into the body portion at a first end and the second adjoining plurality of duct members are insertible into the body portion on the second end, the first and second portions of ducts being slidably engaged into the body portion and meeting substantially at a center point within the body portion, for defining a continuous pathway within the ducts for housing transmission lines therewithin.
