Intel 'Light Peak': not an Apple idea after all

Why hasn't Steve taken credit?

Intel's newly announced 'Light Peak' optical interconnect wasn't developed at Apple's instigation as has been claimed.

So says a mole cited by Cnet, and we're not at all surprised, for a number of reasons.

Intel has been working on various technologies relating to the integration of optical data streams into computer systems for some years.

We recall getting a briefing on so-called 'silicon photonics' - the production of CMOS chips capable of converting electronically transmitted data into laser light and then back again - back in 2006 at Intel Developer Forum.

Light Peak doesn't directly involve silicon photonics products, but it's clear the chip maker has been thinking about optical interconnects for longer than a casual chat between Steve Jobs and Paul Otellini might have prompted.

A year later, at the 2007 IDF, the USB 3.0 Promoter Group - the membership list includes Intel - were already talking about the possibility of incorporating optical technology into the bus standard. SuperSpeed is here - well, almost - and its entirely electric. It's not clear why optical never made it into the final cut, but the time it has taken to get optical ready suggests the minds behind SuperSpeed felt it more important to get the faster bus standard out into the market quickly than wait for what may now well form the basis for USB 4.0.

SuperSpeed has a theoretical maximum throughput of 4.8Gb/s - Light Peak will kick of at around 10Gb/s and has scope to be extended to 100Gb/s.

Certainly, Intel's recent Light Peak demos used a connector a lot like a USB A port and probably not so very different to this:

USB 3 optical connector
Optical USB 3 circa 2007

But more to the point, perhaps, would Apple really hand all this over to another company? It has always enjoyed a healthy stream of royalties - originally $1 a port - from the development of the Firewire - aka 1394 - bus and we can't see it passing up a similar opportunity to own intellectual property rights to a future optical interconnect. ®

But...

Who cares who's idea it was?

Or do we need to know who to blame if it doesn't take off?

And if it doesn't take off then why would we care about blaming someone over something that doesn't matter?

hmmm

Perhaps they mean, they're not suprised now. An hour ago they were, but now that they've had breakfast, it seems completely reasonable (especially now that they know the truth.) Either way, it's a great way to push out articles. "Confirmed! Microsoft releases source code for Windows 7" shortly followed by "Microsoft obviously didn't release source code for Windows 7"

Apple Uses Intel 7 Intel has marketing & Need.....

Thought it sounded fishie, yet porported reason is in header.

Perhaps just apple iPhone that was connected to Blazing wires & writer went too far. TIME WILL TELL.

@jubtastic1

No one said the connector was entirely optical.

USB4 = USB 2 plus optics?

I hope the final Light Peak port isn't that shape

The worst thing about USB is that you can't tell which way up the plugs are. If we go to optical without fixing this, we'll be spending the rest of our lives staring at USB plugs to work out which way up they go. A terrifying thought!
