In fibre-optics, they have cladding, which is a boundry outside the core that has a lower refractive index than the core itself, so the useful range of the core is reduced and the pulsese don't overlap and scrambling doesn't happen. RE: fibre optic cladding by TReKiE on 03-18-2006 at 10:33 PM

I believe that since the light wave has been refracted into the cladding, it's simply "lost" as you already know. I guess your real question is, why is it lost? The answer is since it has a lower reflective index (if you Google, you'll get the equations), it cannot reflect the light thats been refracted into it and therefore it can't reflect back. RE: fibre optic cladding by rav0 on 03-18-2006 at 10:40 PM I kinda know about this, but I don't understand what your question is. Could rephrase it please?

well you have the cladding, and the point of the cladding is to get rid of any light which has an angle outside the tolerance cone thing. RE: fibre optic cladding by Wabz on 03-22-2006 at 12:56 PM

Which brings you to the TCP/IP protocol and whats called the 3 way handshake which is the way TCP error checks , in essence the dodgy light would cause an error and the computer recieving would send a message saying "Send me that again it wasn't correct" |
