13. Fiber Optics
Build the circuit and place the ber optic tree on
the colorful LED (72). Press the switch (62), the
colorful LED (72) will turn on and you will see the
ber optic tree (40) change colors with the LED’s
colors.
If you look at the tips of the bers at the top of the
tree you will see bright light emitting from the bers.
This demonstrates how bers carry light, and the
simplest form of bers (called single mode bers)
can actually carry light over 60 miles or more.
14. Fiber Optic Communication
Build the circuit, press the press switch (61), the
colorful LED (72) will ash. Hold the press switch
(61), the colorful LED (72) will stay on while the
ber optic tree (40) changes colors with the colorful
LED (72). By pressing the press switch (61) ON and
OFF for different periods of time you can simulation
a digital communication signal (light ON means a
digital 1 was sent while light OFF means a digital 0
