  • Patent number: 6787697
    Abstract: A cable channel filler or spline and a cable containing the cable channel filler or spline in its core. The channel filler extends longitudinally and has a plurality of spaced longitudinally extending open pockets in which cables, such as unshielded twisted pair cables, are placed and form part of the core. The core containing the twisted pair cables in the pockets is jacketed. The longitudinal pockets have a cross-sectional area that is greater than the envelope diameter of the twisted pair cable to be placed in the pocket. The channel filler has an imbedded shield that extends into each of the channel filler pocket legs and is preferably prepared from a single tape. Alternatively when two tapes are used for the shield, the first tape has three shield legs and with one leg being a folded over leg and the second tape forms the fourth leg and has 20 to 50 percent—at least {fraction (1/16)} in. of one of its sides encased by the folded over portion of the first tape.

The channel filler extends longitudinally and has a plurality of spaced longitudinally extending open pockets (128, 130, 132, 134) in which wires (42) or cables, such as unshielded twisted pair cables, are placed and form part of the core. The core containing the twisted pair cables in the pockets is jacketed. The channel filler has an imbedded shield (136) that extends into each of the channel filler pocket legs and is preferably prepared from a single tape. Alternatively when two tapes are used for the shield, the first tape has three shield legs and with one leg being a folded over leg and the second tape forms the fourth leg and has 20 to 50 percent or at least {fraction (1/16)} inches of one of its sides encased by the folded over leg of the first tape.
