In this, the last installment of the third series of Bill Hammack’s wildly popular Engineer Guy videos, Bill exposes the wonders of fiber optics. He starts by demonstrating transmission of laser light through a fiber optic stereo cable, then explains total internal reflection with a really cool visual aid made from a bucket of antifreeze. There are details on the manufacture of the fibers themselves, the design of the first transatlantic fiber optic cable, and the signal processing used to encode data for transmission via fiber. All that, and more, in just five minutes and thirty seconds, and with Bill’s usual class. Nice way to wound out series #3!

Series #4 is scheduled for Fall of this year, and Bill is preparing a companion book that will be available as a $0.99 download. Sign up here to be notified when it becomes available.
