Problems solved by technology

Other cables have implemented complex discontinuous EMI barriers and strips in an attempt to control alien crosstalk and ground current interruptions, but the expense adds significantly and may actually increase alien crosstalk in some implementations
Fully shielded cables, such as Foil Unshielded Twisted Pair (F / UTP) designs include drain wires for grounding the conductive foil shield, but are much more expensive in total installed cost when shielded connectors and other associated hardware are used
Also, fully shielded cables are more difficult to terminate and can introduce ground loop currents and noise if not properly terminated

Embodiment Construction

[0040] The present disclosure solves the problems of cable-to-cable or "alien" crosstalk (ANEXT) and signal return loss (RL) in a cost-effective manner without requiring larger, stiffer, more expensive, and more difficult cables than typical cables Design trade-offs for continuous manufacturing. In particular, the manufacturing methods and cables disclosed herein reduce inner cable RL and outer cable ANEXT coupled noise via two strip application design methods to meet American National Standards Institute (ANSI) / Telecommunications Industry Association (TIA) 568 category 6A (category 6 amplified) specification.

[0041] First, in one embodiment, the Fixed Tape Control (FTC) method applies a barrier tape helically around a cable comprising pairs of unshielded twisted pair (UTP) conductors with a filler ensuring dimensional stability for Improved internal cable electrical performance. The FTC method precisely controls the placement and angle of the edge of the barrier strip on ...

Abstract

The present disclosure describes two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable, Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape applicationangle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, alien crosstalk and return losses are improved, while the filler allows a cylindrical shape for optimized ground plane uniformity and stability for improved impedance and return loss performance.
