CWmike writes "Intel's Thunderbolt high-speed interconnect technology could be years away from getting optical technology, an Intel executive said this week at IDF. Originally introduced in February on Macs, Thunderbolt was pitched as being optical technology but currently uses copper wires. Dadi Perlmutter of Intel's Architecture Group said copper wires are working much better than expected, and that fiber was expensive. 'It's going to be way out,' Perlmutter said. 'At the end of the day it's all about how much speed people need versus how much they would be willing to pay.'"
