If CAT 6 UTP cable can achieve speeds of 10 Gbps, CAT 7 UTP cable can achieve speeds of 100 Gbps, and CAT 7a UTP cable will achieve speeds beyond that, why will Intel need to move to light to achieve higher speeds for their Thunderbolt (Light Peak) technology? Why reinvent the wheel, Intel?

PS. I'm sure I could probably find the answer on Google, but I want to see what people here think! Good opinions can't always be found with an algorithm!

Here's why Intel "reinvented the wheel" CAT 6 UTP and CAT 7 UTP only carry data this is while Intel's Thunderbolt cables can carries data, video, audio, and power all over one connection this makes the technology 4 times as useful for the standerd consumer until we need to start transferring data at 100Gbps then the cable is still useful for audio, video, and power. So even though CAT 7 UTP can achieve faster data speeds it doesn't and probably wont ever carry power, audio, and video too. So in sort Intel didn't reinvent the wheel they made a better one.

What I'm getting at is ... Why go to light, when it's been demonstrated that copper is capable of carrying bits at this speed and greater? The main reason network cabling uses light instead of copper is for greater distance, not throughput, nowadays.

Ok so I have a cable1 that can carry one of the 4 main types of data carried through cables. This cable can carry this one type of data faster than another cable2, but the other cable can carry all 4 of the main types of data. Which cable do I choose? I choose the cable that can carry all four types of data. Why you ask? I choose Cable2 because Cable2 uses light, and is theoretically capable of much faster speeds, and is also much more useful to me as a consumer because I now only need 1 cable to carry everything to and from my computer.

To make the wheel a lot better, djmoore.

Or would you rather chug along with stone wheels attached to your car?

As stated above, what does light do right now in short distances, that copper is not capable of in terms of speed? If the stone wheels can turn just as fast, if not faster, why change them? LOL

Because the stone wheels break, don't do as much, and aren't nearly as fast as new rubber wheels.

Light travels farther without signal loss and speed drops. Intel has said that while it is releasing at that speed it could go immensely faster.
