Live next to a power station? Gefen's all-fiber DVI and HDMI cables are for you

If you're concerned about the EMI (electromagnetic interference) monster behind your TV interfering with your pristine digital HDTV signal, or just like putting your TV 100 feet away from the source, Gefen has got the cable for you. Made out of all fiber, it is extremely resistant to degradation due to length and interference, and extends the cables well past other manufacturers limits. Wireless or wired, Gefen seems to have HDMI for every possible occasion.

Of course, you're going to pay for the privilege, no price listed for HDMI but the DVI cables start at $400 and go up to the thousands depending on length.
