The link below shows the connection diagram between the OLT and the ONT and the Router.
The
HUAWEI MA5671A transceiver is the Optical Network Terminal pre-configured by Bell and initialized when the HH3K is first installed in the client premises. After the CPE [HH3K] is installed the GPON Transceiver can then be removed from the HH3K and then put into your Tilk Router's SFP port -- this is in ONTARIO and QUEBEC only because Bell Ontario/Quebec uses GPON. And one still needs to configure the VLAN's for Internet, IPTV and Phone all depending on the service one subscribe too.
Atlantic Bell uses EPON .... this means that you take the Ethernet cable coming out of your ONT and plug it directly into your Tik's designated Ethernet port for WAN. You still need to configure the VLAN's for Internet, IPTV and Phone all depending on the service you subscribe too.
Your CCR1009 SFP+ cage to copper converter does not work because there is a Ethernet mismatch or there is some other issue in the conversion to Ethernet .... so if you want to use that port for WAN MilroTik will need to fix the issue ... BUT because your BELL connection is EPON and NOT GPON then why bother with the SFP when the Ethernet port will work perfectly.
