Sure there were issues, but the OMCI specification got updates and BBF also 
tests ONTs

That is a small list, but not every vendor will do it for every device, maybe 
RFP driven to get a BBF certification.

If you get a current device I would just test it and wouldn't change the OLT 
vendor, if it works as expected.

Kind regards
