crosstalk

 [kros´tawk]
in cardiology, inappropriate detection of the atrial stimulus by the ventricular sensing mechanism, usually seen with dual chamber pacemakers; it can lead to asystole. Pacemakers are now able to respond to crosstalk with an obligatory ventricular pacing stimulus at a shorter than average A-V interval.

crosstalk

An artefact in MRI images caused by interference between adjacent slices of a scan, which can be reduced or eliminated by limiting the minimum spacing between slices.

This design reduces the weight and diameter of Category 6A UTP cables, improving pathway capacity up to 30% for improved airflow through dense data center enclosures without compromising alien crosstalk performance.
Alien crosstalk can come either from sources at the same end of a transmitting link (alien NEXT), or from sources transmitting at the other end, or somewhere along the length of the link (alien FEXT).
If the cabling has a measured DB margin, then you can assume alien crosstalk is met by design.
The blocks allow for staggered pair-to-pair arrangements in multiport designs to reduce alien crosstalk, while a notched-head design secures wires in plastic housing prior to termination for a stable contact connection.
In addition, the system eliminates the need for costly Alien Crosstalk field testing while improving space utilization in horizontal and vertical pathways.
This next-generation end-to-end Category 6A UTP system provides significant margin on all 10GBASE-T electrical parameters with improved alien crosstalk performance, delivering superior overall channel performance over a slimmer UTP cable.
Siemon says that the drawbacks include; a sensitivity to alien crosstalk through mishandling or poor installation practices, a higher potential need to perform time-consuming and complex field testing for alien crosstalk to trouble shoot unshielded twisted pair channels and length de-rating based on higher temperatures, which can reduce unshielded twisted pair lengths for full compliance to category 6A insertion loss requirements.
