I took an introductory fiber optic class at my local supplier's this evening. Pretty informative, and I got to make a splice (the gel type, no polishing!) Since I was the first volunteer (why will no one else volunteer?) my splice was actually pretty bad, but I was informed that it still complied with the 20dB range... (I tapped a little to hard on the little doo-hickey that nicks the cable at the proper length, and I probably chipped the face a little...)
My main Q is on the theory that I was told of transporting power
How is the electrical power converted to light and back? My joke was that is was a bulb on one end and a photovoltaic cell on the other, which would be horribly inefficient... How do they really do it?
How much "light" power does it take to make "x" watts of electricity? I'm under the impression that light and electricity are both electro-magnetism, are they just at different frequencies or is it a bogus comparison? How does it relate?
Was this guy just blowing smoke?
(And will I need to trade in my tools for fiber optic kits?)
