With early PON designs, upstream bandwidth was horrible. Not 
particularly useful if you're doing things like remote backup, or video 
chatting, or running a server (business grade service). GPON does better 
on upstream bandwidth, but it's still asymmetric.

If you're marketing to business customers, or home office professionals, 
of families with multiple users that consume upstream bandwidth, AE 
gives you a lot of room for upside growth (assuming you provision the 
right kinds of fiber).


In theory, there is no difference between theory and practice. In 
practice, there is. .... Yogi Berra
