Fiber Optic Cables

(YouTube link)

Bill Hammock, the Engineer Guy, explains how fiber optic cables work. I, for one, am amazed that glass can be spun thin enough to be flexible, and that light can travel through it around bends and corners. -Thanks, Bill!

If the signal was analog however it would need to be repeated much more often and signal loss would become a major issue. That binary can be decoded by mapping each octet onto their respective numbers in the following chain from left to right 1/2/4/8/16/32/64/128 and adding the corresponding values together and then referencing them on a UNICODE chart. 01101010 becomes 0+2+4+0+16+0+64+0=86 which corresponds to the Latin capital letter V. This can also be transcoded to hexadecimal in which the same letter is represented by a 4 digit "nibble".

I find this stuff very interesting.
