Big World Of Wonders

Fiber optics are amazing! It's hard to conceive what they really do. It actually starts with the vibration of your voice. An encoder machine measures the sound turns it into a current then the machine digitally codes the electrical signals. It is then turned into different tones of light transmitted acrossed a laser sent across the fiber optic cable. And if you understand that you're doing better than we are! (hehehe) You have to read the whole book on the subject and then your mind still can't grasp the situation.
