I just wanted to ask if we can use any kind of ONT/ONU for BSNL FTTH just like ADSL modem/routers.

Hard to say if it will work with any type of ONU. See following video but it doesnt say for sure:

So from the video it seems the OLT for GPON vs. GEPON are different, so I am guessing you need to make sure that if your telephone exchange has GPON OLT then you can use any GPON ONT but if exchange has GEPON OLT then you need to use any GEPON ONU modem.

My LCO vendor provided me with a GEPON modem so I think my telephone exchange has GEPON OLT installed. Maybe some day I will ask them what company OLT is there.

GEPON max downstream is 1.25 gbps and for GPON max downstream is 2.5 gbps, for both upstream is 1.25 gbps in the video

At the 14 minute mark in video the guy says Syrotech has a ONU which works for both GPON and GEPON OLTs :D

@Nikhil Sharma How did you finalized the ONT? My LCO says we don't have buying option (don't have any knowledge). I want to buy one so please guide. OLT in LCO office/BSNL office needs to be of same company? They said OLT (they call it machine) is from BSNL itself.

We can give you configuration but won't be able to configure as every ONT is different. Any inputs will be greatly appreciated.
