40 Of Verizon's 600 CO's are GPON > just because..

Just because the Central Office becomes gpon capable doesn't mean that they will automatically swap out everyone's ONT from BPON to GPON in due course.. These systems were designed to be backwards compatible. The GPON ONT upgrades are on an as needed basis... so they actually does little nothing to provide any meaningful competition to the forefront in areas that already have FIOS. Unless your getting the triple play FIOS with their top tier FIOS internet your probably not going to see GPON ONT if you have BPON any time soon.. & I've heard this from techs as well as the door to door salespeople.

You must be talking about the Motorola ONT being backwards compatible, most BPON was built with telelabs that is not and will need to be replaced.

Rather, what I meant was.. even though they replace the CO equipment with GPON capable line-cards, etc. the end ONT's don't automatically have to be replaced unless necessary. In other words, they don't have to swap out 100% of the customer premise ONT's to GPON if a CO is GPON. Strange to learn that GPON line cards modulating a BPON signal wouldn't be compatible with BPON ONT's from another manufacturer.

** They couldn't be that stupid, as to make things difficult for them, now would they?

That is not how it works - BPON ONT's will not work on a GPON line card and vice versa...and interoperability is not ready yet..So only the same manufacturer's ONT will work on the same manufacturer's line card.
