Cat7a, also known as Category 7a, was introduced by ISO 11801 Edition 2 in 2010. In comparison, earlier standards offer lower frequencies and data transfer rates. For instance, Cat7
operates at a frequency of up to 600 MHz and supports data transfer rates of up to 10 Gigabits per second, whereas Cat7a operates up to 1000 MHz, more reliably achieving data rates 10 Gbps and beyond. In terms of physical differences, Cat7a cables are thicker than Cat7 due to the additional shielding used to reduce signal interference. This shielding also requires a specialised GG45 connector, which is backward compatible with the RJ45 connectors used by Cat6 and earlier standards. Cat7a has limited technical standardisation and adoption as it represents only a marginal improvement over Cat7, and became widely replaced by the Cat8 standard introduced in 2016.Max. Bandwidth
