Thanks

Only if you use modules like this:

It says GPON. does it support gepon?

You missed my point - GPON or GEPON any "passive" part must be implemented build-in on the module, board itself doesn't support it. So if you will be able to find SFP module that makes the transfer - you will be able to use it. So far that video is best lead i have.

There are some units around which *may* have the required functionality but I have not had a chance to test them yet.

e.g.
