How do computers do in sending and reading data coming from fiber optics?
In: 1
Just like sending a Morse signal with a flashlight. You put a light source on one end, and light detector on the other, and blink the light very very fast.
You can do that with multiple colors at once to put even more signals at once.
Now fiber optics are kind of like a tube made out of mirrors, so light bounces on the sides and stays in the tube until the end.
Fiber optics are limited in speed/length, not because of how fast you can blink the light, but because part of the light from a single blink will go straight trough the middle of the tune, while part will bounce around more. So if you send your blinks too fast, the bouncing part of the first blink will take longer than the straight part of the next blink and mess the message up.
But fiber optics are still way faster than wires because light is really fast, and they aren’t messed up by electric and magnetic noise like wires are.
