GPON Qos and optim

Hi Every one ,

Thanks for the owner of this forum and all the community.
I’have a question about QoS KPI optimition in the GPON : what are your recommandations for getting a best line quality knowing that we have a full charged PON tree of 64 users (ONT) ?

2nd question is related to the number of T-CONT to implement: what is the relationshipp between number of TCONT that we configure ( 1 TCONT, 2 TCONT, 3 or …5 TCONT) and the bandwith allocation( DBA), line speed, latency & gigue ?

I hope I get a feedback !

Thanks all of you in davance

Best Regards
