Shielded Cabling: Eliminates alien crosstalk so field testing is never required
Alien crosstalk is defined as: Unwanted signal coupling from one balanced twisted-pair component, channel, or permanent link to another. (I.E: Cable-to-cable interference)
AXT is seen at higher frequencies such as 10GBASE-T and is more problematic in unshielded (UTP) systems. The noise coupling occurs on like pairs (for instance blue-white to blue-white) as they will have roughly the same twist lay.
This is not a concern with screened or shielded systems as the shield prevents alien crosstalk from affecting adjacent cables.
