For initial Light Peak, copper may be better than a sharp stick in the optics

CNET's Brooke Crothers is reporting that for its initial version of the much-ballyhooed Light Peak, Intel will use electrical- rather than photonic-based circuitry. To you and me, that means copper rather than fiber.

Light Peak will be a 10-Gbit/sec technology connecting electronic devices, and threatens to supplant USB as the connection-technology of choice. Sony and Apple have supported the Intel technology, which should still roll out as anticipated in the first half of 2011.

I was particularly interested in Crothers's notation that despite the use of copper rather than fiber, Light Peak will still achieve its stated 10-Gbit/sec transmission rate. What do you know about that?
