content: Just saw that on YoutTube:I don't have any practical use for it, but this is still pretty cool. Especially the claimed durability of the cable.http://www.corning.com/opcomm/OpticalCablesbyCorning/products/USB-3.Optical.aspx#.VDU5bPmSwqx

content: Optical USB3.0 cables have been out for a while, though I guess not in that length.The problem is COST- its over $300 on Amazon. Even the 10 meter cable is over $100.Not sure I get it... What's the use case? Maybe if you could use it for video, but I'm not aware of anything that can send a video card's output over usb3.Cat6a will get 4x the throughput of USB3.0 over the same distance (10 gigabit full duplex versus 5gigabit single)... But I guess the 10gigE NICs are more money in the end.

content: USB 3.0 is full duplex. And USB 3.1 is 10 gigabit, though there are few applications for the increased speed at this time.

content: I actually have 10 meters (30+ feet) between my two PCs and my desk so everything can be in the next room over, out of earshot. But I'm using boring old copper cables with the exception of the toslink audio. The dual-link DVI cable is as thick as my thumb. I'd love to have something like this, especially since adding another monitor would make the bundle of cables even more unmanageable, but I've wasted enough money on this silly project already.

content: Quote from: NiHaoMike on October 08, 2014, 02:52:53 pmAh, I didn't realize that it was full duplex. These cables are not listed as supporting 3.1, though.Quote from: gxti on October 08, 2014, 05:18:00 pmThunderbolt would be more up your alley since it can carry Displayport signals straight from your GPU. On USB3, you'd be stuck with with displaylink's crappy software-kinda video acceleration. However, optical Tunderbolt is even more expensive- 100 foot is $650, and you can't just add Thunderbolt to a PC without it. You could, though, plug the cable straight into a Mac monitor and get everything at once. Mac monitors have Audio, USB, and even Firewire.Of course, Mac monitors aren't silent- the only LCD monitors with fans that I know of.

content: This is a quote from their website."two copper conductors transmit power from the host for the optical to electrical conversion and back again. All data is transmitted over the optical fibers. "Does anyone know if that means that there are NO copper wires run in the cable. Only optical? If so, they should have an option for a shorter 3-6 foot cable.That would make a great high speed optically isolated USB cable with a reasonable price. I have been looking for one to isolate my USB3 hub from my computer without spending an arm and a leg. I can't find anything on the market that run at USB3 speeds.
