Our CAT6A Cable Shielded is in-stock in warehouses within the United States, saving you both time and money by reducing shipping costs. These ROHS compliant CAT6-A (The A stands for Augmented) cords are STP cables, which stands for Shielded Twisted Pair, meaning they reduce outside interference. They also exceed ANSI EIA/TIA 568 B.2-10 specifications outlined here. When compared to our other products, such as CAT6 v CAT6a, the CAT 6a wiring is noticeably faster and is ideal for 10G networks. On the other hand, standard ethernet cable category CAT6 speed can also reach 10G, but loses speed more quickly than CAT6A cables do as the cabling gets longer. You can view the different types of ethernet cables, such as CAT 5 wiring and UTP patch cables, we sell by clicking on the Networking tab above or by reading about their differences here: https://www.cablesforless.com/network-cables-explained/ or check out wikipedia.
