it's all about ones and zeros. When the laser is on, it's a one, when the laser is off, it's a zero. All computers work with nothing more than ones and zeros and telecommunications is loaded with computers. The advantage to lasers is it is light so the information travels at the speed of light and it can be focused tightly and aimed precisely.
