Of more direct interest, though, was the practical side of things. After the rather overwhelming tour of the labs, I was finally allowed to play with Light Peak myself probably, in fact, on the very same laptop that Barry had already seen in Brussels. As he noted at the time,
prototype Light Peak hardware runs over a hybrid USB 3 connector, with an optical interface embedded alongside the electrical one:
Mr Paniccia stated several times that this hasnt been confirmed as the final connector for Light Peak; but its clearly an ingenious marriage,
combining the new technology with legacy USB compatibility, plus an electrical connection that can be used for power (which, of course, cant be carried over a pure optical link). I would guess Intel is being cautious not because it reckons it can do better, but simply because it hasnt yet secured approval from the USB standards body for this rather radical upgrade to the standard connectors.
