FTTH Active vs Passive

[luke.marrott at gmail.com (Luke Marrott)]

I'm wondering what everyones thoughts are in regards to FTTH using Active
Ethernet or Passive. I work for a FTTH Provider that has done Active
Ethernet on a few networks so I'm always biased in discussions, but I don't
know anyone with experience in PON.

I've read before that almost all PON technology is proprietary, locking you
into a specific hardware vendor. However I think this is changing or has
already changed, opening PON up for interoperability. Can anyone confirm
this?

Thanks in advance.
