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.
Reduced costs by removing the need for overlength cable in data centres* Guaranteed no '*' pass results during field testing due to massive headroom* No Alien Crosstalk
( ANEXT ) field testing required* Easy and cost effective installation thanks to system tolerance* Interoperability due to component compliance
Because signals higher than 300 Mhz begin to propagate beyond the cable to affect adjacent cables, this alien crosstalk
interference is often the limiting factor in running 10GigE on cabling.
Typical UTP Category 6 cabling systems are hindered by the technical combination of insertion loss and alien crosstalk
(interference from adjacent cables) at higher frequencies.
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 alien crosstalk
testing took 18 hours per TR to complete the 15 tests.
Nexans is prepared for these developments with its Cat 6A Zero Risk Solution based on shielded products that ensure immunity from alien crosstalk
The four pair TERA to BladePatch version utilizes high-quality category 7A stranded cable and meets or exceeds all 10GBASE-T standard requirements, including all alien crosstalk
SYSTIMAX Labs utilized its unique Modal Decomposition Modeling (MDM) tool to evaluate the 1,024 interactions between adjacent, as well as within individual, cabling components to achieve substantial reduction in alien crosstalk
(ANEXT or noise from adjacent cables and connectors).
Backed by CommScope's Uniprise 20-year warranty, Uniprise Ultra 10 systems extend bandwidth without degrading internal channel transmission performance by suppressing interference from external pairs to eliminate alien crosstalk
at frequencies up to 500 MHz.
The first topic that was discussed was 'Is alien crosstalk
testing needed for Cat 6A cabling?
The patch cords utilize Category 7a stranded cable and meet or exceed 10GBASE-T standard requirements, including alien crosstalk
