How Does LIGHT Carry Data? - Fiber Optics Explained?

Light can carry data through fiber optics, just like how water can carry a message in a bottle.

Imagine you're sending a letter to your friend by putting it inside a bottle and tossing it into the sea. The bottle travels across the water, and when your friend gets it, they read the letter. In this case, the bottle is like light, the water is like the fiber optic cable, and the letter is like the data you're sending.

Fiber optics are super thin wires made of glass or plastic. When light travels through them, it can carry information, just like how a message in a bottle carries a note from one person to another.

Instead of letters, we use pulses of light, quick flashes on and off, to send data. These pulses are like the taps you make when you're sending secret messages by tapping on a desk. Fast taps mean one letter; slow taps mean another.

When the light reaches the other end of the cable, special tools read those fast and slow taps, turning them back into something we can understand, like a video or music. It’s like your friend reading the message in the bottle and knowing exactly what you wanted to say!
