Apple Behind Intel's USB Competitor?

We recently discussed Light Peak, Intel's upcoming, optical interconnect technology that boasts data transfer rates of up to 10 Gbps. While some have speculated that Light Peak will directly compete with USB 3.0, Engadget has now unearthed information that indicates the idea for the technology originated from Apple, who apparently asked Intel to develop it. "According to documents we've seen and conversations we've had, Apple had reached out to Intel as early as 2007 with plans for an interoperable standard which could handle massive amounts of data and 'replace the multitudinous connector types with a single connector (FireWire, USB, Display interface).' ... Based on what we've learned, Apple will introduce the new standard for its systems around Fall 2010 in a line of Macs destined for back-to-school shoppers — a follow-up to the 'Spotlight turns to notebooks' event, perhaps. Following the initial launch, there are plans to roll out a low-power variation in 2011, which could lead to more widespread adoption in handhelds and cellphones. The plans from October 2007 show a roadmap that includes Light Peak being introduced to the iPhone / iPod platform to serve as a gateway for multimedia and networking outputs."

      Except that no, you're wrong.

      Why have you so quickly forgotten USB?

      Mice: used to be serial or ps/2; now: USB.
      Keyboards: serial, ps/2, AT; now: USB.
      External CD drives: used to be SCSI or whatever; now: USB.
      External HDDs, the same, even if some enthusiasts also use eSATA.

      And I'll bet you have nothing at all to say about the hundreds of other little thing that use USB. Phones, flash drives, webcams, tv tuners, wifi, ethernet, bluetooth, and SO MANY MORE things I can't even remember much less have seen before.

      USB promised to "replace the multitudinous connector types with a single connector" and succeeded.

    The iPod already uses a special connector. You could just make an integrated cable with power and an optical data link, the same way USB and Firewire now use a cable with data and power links.

    Actually, they'd be nuts not to just spec the cable to have power anyway. It's not going to be nearly as popular if suddenly everyone has to start carrying around wall warts for their external drives.

    Yes.

    Transferring a 100 MB app to my iPhone takes a noticeable amount of time, for example. A movie is worse. And things will get MUCH worse in the future, when we have higher resolution portable devices.

    And what Apple wants to do with this interconnect is to replace things like DVI/Display Port, Firewire/USB, (e)SATA, etc., all on one bus.

    I think the idea is to have a homogeneous connective form factor for all data connections on the computer, so that all cables are interchangeable. As far as I know, the bandwidth of an optical transmission isn't limited by the transmitting medium itself, but by the interpretative hardware on either end, which is improving as defined by Moore's law. So you set a standard for the cable and connector now and create interchangeable cables that are not device-specific, which results in all changes to the technology occuring completely on the backend, out of sight to the user.

    If this is, indeed, the goal of LightPeak, i *really* hope that they learned a lesson from USB, and make a connector that can be plugged in using tactile feedback, rather than requiring the user guess-and-rotate as is the case today.

    You don't have to buy a $40 HDMI cable. If the cables you buy are that expensive, then you're just getting fleeced. Do the barest amount of research before you purchase.

    Also, the cheap HDMI cables are more expensive than "ethernet patch cables" because of licensing, a more expensive connector, more wires, and more stringent requirements on the quality of materials. The cable costs more than a dollar because it's the equivalent of several CAT-6a cables. It's designed to transmit raw video data at 1920x1080p30. That's roughly 1.4Gbps. The standard even defines faster rates. You'd need 2-3 CAT6a cables to transfer video at that rate and still cover everything else HDMI takes care of.

    I think this is probably what Apple is after. As I look at my Macbook Pro, I have the following connectors: MagSave (power), Ethernet, FW800, miniDP, USBx2, SD card, line-in, and headphones. You could probably get rid of Ethernet, FW, miniDP, and USB and replace them with Light Peak. Since I'm rarely using more than two of those at a time, you could probably reduce the number of ports and start shrinking devices.

    The other thing that Apple seems to be targeting is the optical drive. I think you're going to see Apple dropping optical altogether, and moving OS delivery to SD cards. Most other software/media will be downloads.

  7. Re:How much is Apple patented? by putaro · · Score: 5, Insightful

    We'll have to see if Apple has learned anything. I first heard about FireWire in maybe 1993. I went to work at Apple in 1995 and met with the people developing FireWire and there was lots of talk about having devices natively support it, yada yada. It didn't make it into shipping Apple hardware until 1999. Besides being late to market, Apple insisted on charging licensing fees to everyone who incorporated FireWire.

    Had FireWire been out in 1996, they might have been able to get away with the licensing fees. Had they forgone the licensing fees in 1999 they might have kept USB a low-speed interconnect.

    In order to succeed in today's market it will need to offer technical advantages over USB 3.0 and not come with a price premium. Having Intel introduce is a pretty strong first step. We'll have to see how the rest of it plays out.

    This is Apple talking. Since when has Apple bothered with legacy connector support?

    So now users can call tech support with their mouse plugged into their monitor and say that their "computer doesn't work".

    I don't understand the fixation on making a completely universal plug. It seems good in theory, but what does it actually get us beyond some cable interchanging possibilities and expensive upgrades?

    Why aren't we working on better wireless communication so that we don't need wires at all? I can't get my wireless mouse 2 feet away from the receiver, and I sure as hell don't want another cable cluttering things up.
