Intel introduced Light Peak in 2009, an optical cable interface that could transfer data at 10Gbps. In 2011, they launched "Copper Peak" which used copper cables instead of fiber optics. Also in 2011, Apple updated the MacBook Pro with Thunderbolt, a strictly copper-based port that could transfer data at 10Gbps and replaced USB and other ports.
