FB - Floor box
If you're wondering what the rest are ...
OLT - Optical Line Terminal (it's the source of data)

"How many other acronyms does this paper have?". 23 on the first 2 pages.
"Is this paper readable?". No. Why do you think I'm making this post instead of reading that paper?
"What is the funniest acronym on this paper?". I think CAB and FB are good contenders. But more funny is that this paper does not make an acronym of "Bob station" or "Alice station". Those must be written out in their full glory each time.
