Bit pedantic, but with HDMI cables, there is an electrical standard that needs to be met at both ends of the cable, but nothing about the cable length. Cable length is one of the more important things that effect a cables ability to meet the HDMI standards...
A well manufactured and quality (an is built in a reliable, repeatable and tested way) using some exotic materials is the secret to getting a 10-15m HDMI cable that actually works.
