USB Reversable Cable Images Emerge

Posted by Soulskill on from the saving-you-3-annoying-seconds-a-couple-times-a-day dept.

Lucas123 writes: "A presentation released today by Intel revealed images of the USB 3.1 Type-C cable and connectors, which is symmetrical and will no longer require a user to correctly orient the plug. Initially, the USB 3.1 Type-C specification will support up to 10Gbps data transfer speeds. The Type-C connectors resemble those of Apple's Thunderbolt cabling in that they are much smaller than today's USB SuperSpeed connectors. The receptacle opening is 8.3mm x 2.5mm.The first iteration will have a 5 volt power transfer rate, but it is expected to deliver up to 100 watts for higher power applications in the future."

    I don't want to sneak peak, but "5 volt power transfer rate" makes strictly NO SENSE. The "volt" is not a unit of power...

    Damn incompetent journalists ...

      IAAP (I am a physicist).
      There is nothing wrong with "5 volt power transfer". It is just saying that the power (whether 100mA or 100A) is always transferred at 5 volts, and not at 0.5 V or 50V. What is strange here is the "power transfer rate". Power= "energy transfer rate". "Power change rate" would make sense when talking about power ramp up, (i.e. how many milliseconds it needs to go from 100mA to 1A).
      A Type-C cable with100W racing through it sounds like a fire hazard to me.

      Realistically, how many amps is thing thing going to allow?

      They're saying 5A at 20V.

      Realistically, I wish the USB-C connector could start at 5 volts but negotiate to 12 volts to offset voltage drop.

      That's mostly what it's going to do. It starts at 5V, and negotiates up to 12V or 20V.

    The 100W case will be 20volts at 5amps

    It's in the Intel pdf file at https://intel.activeevents.com/sz14/connect/fileDownload/session/3446B9E71F4FD3D70D8FB478DA239801/SZ14_HSTS002_100_ENGf.pdf

    You obviously never had to actually deal with serial and parallel connectors and their little screws to hold them in place.
    USB was a freaking godsend!
    Of, things can certainly get better, but companies hate jumping into new territory and would rather do it one increment at a time, if they can't avoid changing in the first place.

    The same document in page 14 limits the 60W and 100W profiles to the A and B type. So the C type is probably limited to 36W.
