Thunderbolt

Post by Chevypower » 04 Mar 2011 22:38

Just wondering if anyone else thinks we should expect a Thunderbolt interface on any upcoming cameras to be announced at CES 2011. It would obviously speed up the workflow immensely.

I doubt if there will be much take-up for a while. Apple is the only promoter at the moment and they represent a minority of computer systems. As far as data interfaces are concerned, USB and whatever the removable media interface is, seems to provide a route for compressed data. HDMI and (HD)SDI create uncompressed signal paths for consumer and professional equipment respectively.
As on-board media capacity expands, we may see USB3 or USB2/3 hybrid ports incorporated, but I can't see any workflow benefits of an arcane interface like Thunderbolt, just like Firewire 800 never appeared outside Apple's offerings.

And the Flash memory chips themselves can only go so far in delivering data at those speeds. 10 Gbits/s each way for Thunderbolt? That's about 4 times USB 3.0 alright. But remember why you have various classes of memory cards? Sooner or later, the memory becomes the bottleneck and raw interface speed may not matter so much at that point.

I'm sure that you meant "NAB 2011" (in April) and not "CES 2011" (which was held back in January), right?

With regard to NAB, Panasonic has already pre-announced some new P2 gear with USB 3.0 interfaces, the AG-HPD24 Deck and the AJ-PCD30 Drive.

It's my understanding that Panasonic was quite surprised at Apple's recent announcement of new products incorporating Intel's Light Peak technology (called Thunderbolt by Apple) rather than USB 3.0.

As to Light Peak/Thunderbolt, I'll be more impressed by the forthcoming optical fiber version than the existing copper wire based version.

Yeah I meant NAB, not CES. Lacie has adopted Thunderbolt also for their solid state hard drives. Rumors are the Canon and Nikon will use Thunderbolt for their high-end DSLRs. Frank, how fast will the fiber optic version be? I thought the current version was fiber optic.

Thought so.

Yes, everyone will soon, if only as a marketing point.

Yes, I've heard that Canon will for certain.

Currently, the same nominal 10 Gbps as the copper version. The copper version has a much more severe cable length restriction than the fiber version: about 1 meter for the copper version versus up to about 100 meters for the fiber version. Of course, the fiber version can't carry power whereas the copper version will carry up to about 10 watts, which can be useful for powering various types of devices. And, of course, the optical version, being optical and not electrical, will neither generate RF nor be affected by RFI.

No, copper only initially. My gut feeling is that Apple pushed Intel to release the copper version when they did - not to mention the change in name. :)

Maybe I'm jaded, but I'm also not particularly impressed with the speed. I mean, 10 Gbps Ethernet (10 GigE) is now quite common in many environments and some folks are running 40 GigE and even 100 GigE networks, although it could be argued that it's not entirely fair to compare a networking transport with a device connection interface.

Ultimately, the fiber version of Light Peak/Thunderbolt may well go at rates up to 100 Gbps.
