USB Reversable Cable Images Emerge

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 believe that's how it works - as 100W at 5V would be 20A, which would cause some problems with cables melting. Start at 5V, and a means for devices to negotiate higher voltages if the host is capable of supplying. Not all hosts will be able to - good luck getting 100W out of a tablet.

      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.

    Seriously, why can't we have cables that fit into each other as well as be symmetrical. Oh wait, that's thanks to the patent system. At least this is progress and maybe we will have one standard for most types of application (not holding my breath).

      The linked patent expired in 2006, so that specific one isn't an issue in this case. Also, round connectors in general are a pain to line up properly and connect.

    I used to worry about high currents thrown around electronics these days. I don't anymore. Check it out:

    - 100 amp mosfets in TO-220 packages with the thin tab. First time I saw this I thought it's going to catch fire. Lots of cheapo UPSes work like this now, and they *do* pass hundred of amps through the flimsiest of materials. So it gets hot, so? It'll last one day past the warranty and that's all it needs to do.

    - Brushless motor controllers for RC toys. 35 amps through 14 gauge wire with 200C silicone sheath. Hey, it only runs for 10 minutes anyways!

    - 180 amp brushless controllers. Motors the size of a Coke can rated for 6KW. Yes 6 kilowatts. Granted, they're water cooled, but I would have thought this is the equivalent of a tankless water heater and the boat could have just worked off the steam generated!

    Obviously, previous design rules WRT to current were too conservative. Look at your dryer plug, and look at a RC boat's (or any battery powered toy) connectors. But I predict fires in any case as manufacturers start counting strands in the wires...

    So when you plug in a cable, the logo on the top is always correct. When it is a sideways plug, you are on your own. :)

    I have a few cables which violate this spec (despite the USB spec being quite clear on this point). I'm not sure if it's a manufacturing error (cable assemblies sent to the molding process upside-down) or the manufacturer just being egotistical ("We want our logo to be visible to the user"). Western Digital, I'm looking at you...
