The Category 6a, or Cat6A plenum cable
is the latest iteration of Gigabit Ethernet cabling. The a stands for augmented and is a nod to Cat6a Plenum improved specifications compared with its predecessor, the Category 6, or Cat6 plenum.

The Cat6A doubles data transmission bandwidth, from 250 to 500 MHz; decreases the chance of crosstalk interference; and provides superior reliability and transmission speeds through greater lengths of cable. Unlike most Cat6 cables, Cat6a cables are also often shielded, making them ideal for industrial use where additional interference may be a concern.

How to Identify Cat6 and Cta6a Cables:

Cat6 and Cat6a cables have their identifiers printed on the cable jacket itself Cat6 or Cat6a, respectively. Another quick way to tell the two cables apart is to note that Cat6a cables are much thicker and bulkier than Cat6 cables
. Note that both types of cables use the same connector RJ45 so that is not a way to differentiate between them.

Wiring:

The latest network cables are made of tightly twisted pairs of copper wires from 4-10 pairs in each cable. Through these wires data is transmitted, but cable length and interference can get in the way of data transmission. More tightly woven wire pairs can solve both problems, or at least improve reliability so one of the biggest differences between older and newer Ethernet cable versions usually comes down to wiring.

Performance Improvements:

While Cat6a does not increase the amount of speed or data transmitted it still transmits up to 10 Gbps it does double the bandwidth frequency at which data is transmitted, from 250 MHz (Cat6) to 500 MHz. This allows for more reliable data transmission, even across greater distances. One of the ways the Cat6a accomplishes these feats is by further twisting the twisted wire pairs around an equally twisted and flexible plastic support. Cat5e Plenum
