![]() ![]() This allows for more reliable data transmission, even across greater distances. 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 higher standard, known as the 10GBASE-T standard, was also implemented to improve the signal-to-noise ratio (interference caused within the cable itself and the peripherals it is connected to) and crosstalk (interference caused by the presence of other nearby cables). 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.Ĭat6 cables were created under a more exacting standard than previous versions of Ethernet cables to facilitate data transmission speeds of up to 10 gigabits per second (10 Gbps). Through these wires, data is transmitted, but cable length and interference can get in the way of data transmission. The latest network cables are made of tightly twisted pairs of copper wires - from 4-10 pairs in each cable. Bottom image displays the additional shielding typically found within the Cat6a. ![]()
