How does a method of communication, say an e-mail or phone call make its way into an underground/underwater fiber optic cable?
In: Technology
Your computer takes the email letters/words and sends pulses of electricity through cables (your network cable, router, modem, cable/phone cables on the street). Those cables lead to the underground and underwater cables. Everything is connected by cables. Just like you can drive anywhere in your car if there are roads connecting you to the place.
Every letter or word has a special pattern of electric pulses, which a computer can understand. Like 0010100 (off, off, on, off, on, off, off) might be a certain letter, and a different pattern is a different letter. So you can send communication through cables using electricity…as long as your computer knows how to encode it, and the receiving computer on the other end knows how to decode it.
I’m leaving out some steps, but that’s pretty much it.
