First is you put shielding, that will suppress alien cross talk, the second way is to physically impose some installation restrictions such as you ensure space between cable or connectors, so you physically separate the two channels so they don't touch and you get some alien crosstalk suppression that way.
The Agilent WireScope Pro delivers desirable near- and far-end crosstalk measurement performance and provides Alien Crosstalk (AXT) measurements, appropriate for testing LAN cabling's suitability for running 10 Gigabit Ethernet (10 GE).
10GigE requires each copper pair be characterized to at least 500 MHz and also has an additional specification for the susceptibility of each pair to crosstalk generated by pairs in adjacent cables (alien crosstalk).
"The addition of the NetClear GTS system provides worry-free, guaranteed 10 Gigabit Ethernet support without hidden distance limitations, uncertainty over Alien Crosstalk compliance, or hassles with long, unwieldy patch cord lengths," comments Dan Kennefick, copper products business manager for Berk-Tek.
The first topic that was discussed was 'Is alien crosstalk testing needed for Cat 6A cabling?' This topic saw the experts express widely differing views on the necessity and benefits of Cat 6A alien crosstalk testing, with the discussion becoming quite heated.
At the time the SYSTIMAX GigaSPEED X10D Solution was developed, engineers at CommScope Labs created unique proprietary design tools to quantify and predict alien crosstalk in the cabling channel - a phenomenon that could not be detected with traditional testing technology.
