What is... fiber?

I see Cox marketing materials everywhere trying to capitalize on the term fiber in one form or another.  My favorite one I've seen recent is our 2GB fiber based Internet.  Reminds me of when I a 0.5m piece of  OM3 fiber patch cable to connect my old switch to the firewall.  At that time I guess you could say I had a fiber based LAN.

Fiber doesn't have to by synchronous. 

OK, fair enough, I'll have to grab more screen shots.  When you go to order services on the business page, you get offered the Small Office/Home Office DOCSIS offerings or the Synchronous Fiber offerings which in the benefits section advertise better (synchronous) upload.  But when I go to choose that option I get offered the asynchronous DOCSIS offerings labeled as above.  I still think somebody somewhere is confused as how we're now being offered the fiber version of the DOCSIS plan we currently have despite Cox fiber not reaching our destination.
