Thunderbolt To Become Standard for PC in 2013, Optical at That
 

Towards the end of 2012, Intel will alter Thunderbolt specification from a copper wire-based interconnect to a fiber-optic or photonic interconnect. An analysis by DigiTimes which takes into account information by industry sources, states that Thunderbolt will become standard for PCs only in 2013, and that too the optical one. This comes even as copper wire-based Thunderbolt is beginning to feature on some high-end socket LGA1155 motherboards based on Intel 7-series chipset.

Thunderbolt will get its big push in 2013, when the port will be standard on mainstream desktops and notebooks by OEM majors such as Lenovo, and several PC motherboard vendors, such as ASUS. The optical Thunderbolt IO, apart from allowing greater cable-lengths than 6 m (a limitation of copper-wire Thunderbolt), could push bandwidth greater than 10 Gbps, as a possible incentive for the industry to facilitate the transition to the optical variant.
