HG8247H PON Light Not Stable on EPON OLT

Hello, Bill22.

It's nice to meet you in the community.
We're working on your problem. Please be patient.

Thanks!

Hello, my friend! 

About the problem you described,

I don't think your hypothesis exists.

The ONT cannot be compatible with EPON and GPON at the same time.

The compatibility cannot be changed through the xPON firmware because the optical modules on the OLT are different.

If you need to convert GPON to EPON, you need to replace the device. 

Hope to help you, thank you!

i have seen in market, people have converted simple Epon device into Gpon/Epon ( means xpon), i have also seen The
Epon Devices converted into Gpon/Epon, they are running on both Epon and Gpon Networks are the same time.

They never changed the Optical Module, in the hardware everything remains the same. they only do it though the Firmware upgrades.

If you could see the attached picture, i have highlighted that both Epon and Gpon modules are being installed on Hg8247H, It means it only needs to be activated to run on Both type of networks.
