BPON will support 50/20. from what I have been offered in my area. I would call sales and ask if 150/35 is available. I am sure they could look it up. Tech support would should also be able to see what type of OLT your line is on, or perhaps what is available out of your CO. You would also need a different ONT. Do you know your model of ONT?
If you want 50/20, I don't believe it is offered in a bundle. NYC is being offered 150/35 bundles from what I read.

BPON can technically do 150Mbps/75Mbps, but the limits with it would be oversubcription, perhaps the OLTs and also the 100Mbps ports on the BPON ONTs. If you're on GPON already, you should be able to get the 150Mbps+ speed already. Best way to tell if your ONT is GPON or not is to check the model number and to also check to see if the ONT has a Gigabit Ethernet port on it. Gigabit Ethernet or particular ONT models are the tell-tale signs of being on GPON.
As far as the difference between the two technologies? From your end you'll see lower latency on GPON (You'll go from say, 6ms on BPON to the gateway router to 1ms or less), more consistent latency on GPON, and higher speeds. I'm pretty sure this is due to how often each device on a split fiber pair can transmit and receive data, thanks to the capacity GPON offers.
Actually 662/155 to the passive splitter if you really want to nail it down. But you can't give the whole OLT bandwidth to a single subscriber, and then as stated, the 100Mb/s ONT port would also be a limit. If you look at the original AFC spec of the OLT and divide that by 32 at the passive splitter, we are already over subscribed. If all taps on the splitter are used.
20.6875/4.428571428571429 if you do the math. That is why it was only offered at 20/5 at one time. Verizon had to do some upgrades to compete with Cable. I suspect the OLT end was changed, and if you wanted higher that 29/25 you had to get rid of your old ONT 610x and move to the 612. So all customers going to Ultimate 35/35 were offered the 612.
Oh well, I don't think I will need 150/35 anytime soon.
APON, BPON, GPON this shows a good breakdown. http://en.wikipedia.org/wiki/Passive_optical_network#Standards
APON/BPON runs ATM. GPON I believe runs more like Ethernet.
" A typical APON/BPON provides 622 megabits per second (Mbit/s) (OC-12) of downstream bandwidth and 155 Mbit/s (OC-3) of upstream traffic, although the standard accommodates higher rates."

Be awesome if ATM + PPPoE was finally killed off. So much overhead and MTU limits suck.
