How do computers do in sending and reading data coming from fiber optics?

In: 1

It’s essentially the same as through copper, it’s just a lot faster.

Data is sent in packets which can be broken down into 1s and 0s, and that data can be easily sent over any medium that can interpret those packets, like fiber.

It’s translates into flashes of light for on and off representing the data that needs to be read or sent. It’s just the semi complicated part of being able to translate it back into data. However, that goes to the same process as turning it into light but in reverse.

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.
