Here comes 5Gbps networking over standard cables
A new Ethernet standard that allows for up to 2.5Gbps over normal Cat 5e cables (the ones you probably have in your house) has been approved by the IEEE. The standard—formally known as IEEE 802.3bz-2016, 2.5G/5GBASE-T, or just 2.5 and 5 Gigabit Ethernet—also allows for up to 5Gbps over Cat 6 cabling.
The new standard was specifically designed to bridge the copper-twisted-pair gap between Gigabit Ethernet (1Gbps), which is currently the fastest standard for conventional Cat 5e and Cat 6 cabling, and 10 Gigabit Ethernet, which can do 10Gbps but requires special Cat 6a or 7 cabling. Rather impressively work only began on the new standard at the end of 2014, which gives you some idea of how quickly the powers that be wanted to push this through.
