Copper vs. optical

Originally conceived as an optical technology, Thunderbolt switched to electrical access to abate costs and to accumulation up to 10W of ability to affiliated devices.15

In 2009, Intel admiral said the aggregation was "working on bundling the optical cilia with chestnut wire so Light Peak can be acclimated to ability accessories acquainted into the PC."16 In 2010, Intel said the aboriginal absorbed was "to accept one individual adapter technology" that would acquiesce "electrical USB 3.0 … and piggyback on USB 3.0 or 4.0 DC power."17

In January 2011, Intel's David Perlmutter told Computerworld that antecedent Thunderbolt implementations would be based on chestnut wires.18 "The chestnut came out actual good, decidedly bigger than what we thought," he said.19

Intel and industry ally are still developing optical Thunderbolt accouterments and cables.20 The optical cilia cables are to run "tens of meters" but will not accumulation power, at atomic not initially.212223 They are to accept two 62.5-micron-wide fibers to carriage an bittersweet arresting up to 100 metres (330 ft).24 The about-face of electrical arresting to optical will be anchored into the cable itself, acceptance the accepted DisplayPort atrium to be approaching compatible, but eventually Intel hopes for a absolutely optical transceiver accumulation anchored in the PC.23
