Cable 6a category

The category 6a increased is a specification of the standard ANSI/TIA/EIA-568-B.2.10 which describes, jointly with standard ISO/IEC 11801:2002 for the correspondence with the class Ea, a type of wiring to twisted pairs, based on the standard Ethernet.

Comparatively with the cable category 6 classifies E, the cable category 6a Ea class is adapted better for the standard 10GBASE-T. This one allows the data transmission flows going up to 10 Gbps and frequencies not exceeding 500 MHz.

Principal characteristics

The table below gives the characteristics for a cable of impedance 100 ohms and length 100 meters.

On this level of flow and frequency, a new parameter intervenes which has a significant influence on the behavior of this type of cable. It is about Alien Crosstalk (paradiaphonie exogenic) which is the electromagnetic coupling between pairs resulting from distinct connections.

Application

The cable 6a category is used for the realization of Ethernet connections in full-duplex mode based on the standards 1000BASE-T and 10GBASE-T.

The connector RJ45 employed for connection limiting the flow and the band-width does not authorize the progression with wiring 6a category. The Ethernet standard evolving to a gradation of the flow and band-width imposes the homologation of category 7 and a new connector industry to go beyond the standard 10GBASE-T.
