4K has pushed copper cables to its limits

Invented in 1880, copper had a great run.

But the demands of modern high-speed applications have exposed its limits. The problem is simple: As data rates climb, copper transmission distance falls. For true 4K video (18Gbps)—which has almost 6 times the bit rate as HD—the maximum error-free distance is just 10 meters. Beyond that, resolution falls off a cliff, leaving consumers ultra disappointed.

HDBaseT runs over copper cables at a rate of 10.2Gbps. What happens to the other 8 Gbps of video data? The best 4K visual experience requires all of the data. Watch 4K content as it was meant to be seen.
