Calix is producing an Active Ethernet ONT combined with residential gateway
router. I believe it also supports TR-069 for remote management.

One other thing I noticed, most seem to assume a pair of fibers per device.
Assuming 1G connection, you can easily use bi-directional optics such as we
use for Active Ethernet and use a single fiber.
