My Internet provider just installed me a 2,5Gbps fiber connection. It arrives with a single fiber connected to a GPON ONT (ZTE ZXHN F6005) connected with an RJ45 cable to the 2,5Gbps port of a 5530 Fritz!Box router. I'd like to bypass both the router and the ONT, do you think that it's possible? For the router my provider says that it's possible and it provided me the connection parameters, but for the ONT I've no idea. I would need a singe fiber SC/APC 2,5Gbps SFP+ adapter that I cant seem to find. Can anybody help me? 'm based in Europe.
