Intel's Thunderbolt transfer protocol will likely remain copper-based - rather than fiber optic-powered - for the foreseeable future.
Intel is reportedly developing a new class of interconnect technology capable of transferring data at up to five times the speed of its recently launched Thunderbolt protocol.
Intel recently confirmed that its Light Peak interconnect technology is ready for deployment.
Intel is reportedly preparing to deploy its Light Peak transfer protocol during the first half of 2011.
Senior Intel fellow Kevin Kahn has predicted that Light Peak technology could eventually replace USB (3) as the industry standard.
