Hey all!

I'm a residential, commericial, and industrial electrician. I have minimal experience with Cat 3, 5, etc... and even less experience with Fiber. My question is:

Is there any class/certification in regards to these types of wiring?
I hear the mention of fiber back bones for token ring setups and things of that nature. What's the best way to learn all the rules and appropriate way to do this type of work?

Any help would be appreciated. Thanks guys!
