Alien crosstalk coupling occurs with respect to both the near end and far end of the installed cabling system.
Topics to be studied include: antennas, the grounding myth, partial and incomplete inductance, intentional and unintentional signals, critical signals, common-mode and differential-mode emissions, crosstalk coupling, multilevel/cascade crosstalk, guard traces vs.
Beyond space savings, users are finding that F/UTP provides increased reliability in retrofit situations, where it eliminates the very-real potential for excessive alien crosstalk coupling between non-augmented cat 6 and cat 6A UTP cables running 10GBASE-T within the same pathway.
BoardSim Crosstalk automatically searches entire boards and builds models for regions where crosstalk coupling between traces can exceed user-defined limits.
The Nautilus family of products offers parasitic extraction, RC reduction, delay calculation, crosstalk coupling noise, IR drop (voltage), and electromigration (EM) analysis.

Alien crosstalk is the exact same phenomenon but the crosstalk coupling now occurs between wire pairs in different, adjacent cabling links.
These features both increase and randomize the distance between a cable and its neighboring cables, resulting in greatly improved Alien crosstalk coupling and Return Loss channel characteristics.
The information required to accurately predict the significance of certain types of ALSR crosstalk coupling is not trivial.
RouteSpecialist models board construction, driver/receiver characteristics and wiring, and generates crosstalk coupling and transmission-line delay rules for SPECCTRA AutoRoute.
