Because Fibre optic cable use light there is no way for RF waves

Ramchandran’s and Willner’s unique approach uses a combination of both these strategies and packs several colours into each mode. Their specially designed fibre optic cables also allow four modes whereas existing cables only have two and can carry a data stream which even remains separate at the receiving end. In their experiment which was published in Science paper, Ramachandran and Willner showed that they could send data via a one kilometre long single-mode Fibre optic cable using 10 different colours which yielded a 1.6 terabits per second transfer rates; equal to 8 Blu-Ray DVDs every second.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 Fibre optic cable use light there is no way for RF waves to interfere with your siginal.  Also because 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  widely used 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.
