Fiber Optic Cables

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.
