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
The computer converts the data to a series of zeroes and ones, which then get converted into electricity on and off/light on and off, then reconverted at the other end.
Not quite the right analogy but think of it as a bit like a fancy SOS signal sent in morse code with a torch, that someone can write down at the other end because they know what the dots (short flashes of torchlight) and dashes (long flashes of torchlight) mean.
