These are unwanted waves of energy that bleed into the siginal of your cable. This happens becuase of the copper inside the cable. Noise can cause interference, distortion, or even loss of siginal. Because Fiber optics use light there is no way for RF waves to interfere with your siginal. Also because QSFP to MiniSAS Fibre optic cable use light they are future proof. HDMI right now can do 1080p, whats in store for 5 years from now? 1080p will be obsolete and if you used hdmi or cat 5 to wire you home you will be kicking yourself later on. Once again since fiber uses light the unlimited bandwith can support resolutions that we dont even know yet. Scientists have been trying to find limititations on fiber since it has came out and have had no success. Its the perfect cable to wire your home with for video switching.
If you look at the ratings for HDMI and Cat 5 you will see the average length for these cables is very low. In fact HDMI cables are rarely found over 50ft. and cat 5 cables are said to have a max distance of 328 ft. This means that you cannot wire your home with HDMI, Mediabridge Toslink it also means some tv locations may also have problems if wired with cat 5. On a previous installation we were able to install 3 tv’s in a guest house that was well over 1/2 mile away. These TV’s had full access to all the media that was inside the main home. This was only capable because of Fibre optic cable.
