Yes, but you still have to drive to the train station and find parking at their garage. My point is the intermediate steps required for this conversion. Your mobo and peripherals and expansion cards are all electrical on the inside. It's very easy for them to communicate over an electronic interface, because their internal circuitry is all electrical. They can just keep pushing electrons around, no need to convert to a fundamentally different interface. With LightPeak, your circuitry is still electrical. You're just converting the electrical signals to optical ones, transmitting the optical ones, then converting them back to electrical so you can use them. I got my "panties in a twist" when a previous LightPeak article claimed it as an advance in "optical computing". LightPeak is not optical computing. No calculations are being done with photons. It's not computing anything, just transmitting data. These letters I type are converted to binary by my computer, sent to your computer, and converted back into English. You and I are communicating in English. We can't speak binary, but our communications are converted to and from binary by our computers. LightPeak is the same idea. The computers aren't computing optically. They're computing electrically, then using a piece of equipment to convert it to optical, then using a similar piece of equipment to convert it back to electrical. My aim isn't to criticize LightPeak. It seems fine and dandy. My aim is to clear up some myths about it. It's not fundamentally a better technology than copper for short distances that the average user would encounter (<100m), and it's not a revolutionary advance in computing any more than being able to convert to and from binary was a revolutionary advance for the English language. Also, I LOL'ed at the picture with the rainbow of light. Optical communication occurs at 1.3 microns and 1.5 microns, both well outside the range of human vision. This is because of a dispersion minimum in fused silica fibers around those wavelengths which reduces pulse broadening and other signal degradation effects.
