Hello, I am planning to take an FTTH connection from Railwire ( India ). They supply their own GPON based ONT. But it is not WiFi enabled. So I will have to go for a WAN router for now. But I wish to support the local franchise by providing WiFi enabled GPON ONTs. I searched Google and managed to get the following diagram. Wondering if someone could help me build one for testing on the network.
