[reboot08] David Isenberg on the end of bandwidth limitations
David Isenberg shows a fiber optic cable with 864 fibers. Each can carry 155 frequencies that each can carry 10 gigabits. That means three of the fibers can carry the entire busy hour traffic of the USA. If everyone on the planet had a phone and was making a call at the same time, that one cable could carry it, and 100 of the fibers would still be dark. [I'm sure I screwed up some of the numbers, perhaps seriously. Sorry. I'm multitasking because I decided this afternoon that my after dinner talk — entirely new — needs slides.] “The answer to the question ‘How many angels can dance on the head of a pin?’, the answer is ‘How many do you want to dance on the head of a pin?’.”
