The fiber is undoubtedly terminated at an ONT which has an RJ45 jack which then needs to be connected to what the ISP usually calls "A Modem". That "modem" is generally a firewall/router and WAP. The exact Ethernet protocols used on that RJ45 connection to the "modem" varie. Some do PPPoE, some just need some sort of authenticating DHCP client, so do other stuff. -- Grant
