Fiber Optics

Fiber optics is a very interesting field. It is the transmission of light over long distances, using a small wire. Actually, it isn’t a wire at all, but long thin strands of pure glass that are the size of a single piece of hair. They group these fibers together and make optic cables.
The cables consist of three main parts. The first part is the inner most part, which is the core. The core is the strand of pure glass that the light is used to travel through. The second part is the clad...
