A brief introduction to fiber optics
It is quite certain that we are going to come across optic fibers while we are dealing with copper cables, so it is a good idea for us to have a brief look at how they work and what they can be used for – as well as what is likely to damage them.
Here are a few answers to questions about fiber optics.
Why do we use optic fibers?
They have some good points. Because they do not conduct electricity they are immune from electromagnetic interference (EMI) and crosstalk however strong the fields and because the glass is an insulator there is no worry about short circuits. Even the strength members within the cable do not have to be metallic. Compared to copper, they have very wide bandwidths and low losses. ...
