Direct fibre cable to VPN 100

Dear all, I have switched to FTTH for the first time in my life. I have a WORKING setup with a Zyxel XGSPON Voip IAD (AX7501-B0) router in bridge mode connected via ethernet to a WAN port on my Zyxel VPN 100. The VLAN (11) is set up on the VPN. All is working fine.

However, as my VPN 100 has its own SFP port I do believe that I should get this to work without the router. I think I should be able to attach the fibre cable directly to the sfp port. I have tried this using the (working) SFP Module of my router (Zyxel PM7000-00 XGSPON SFP+ Type SFU). I have also changed the VLAN base port to SFP on the VPN 100 etc... however, nothing happens. The SFP port does not even come to life, the web interface does not show that a cable is connected. With the WAN/LAN ports, you see where a cable is connected.

I do not understand what I am doing wrong. The router does nothing except converting the signal to ethernet, which is what the VPN 100 could do by its own.

Any hint/help is greatly appreciated!

    Hi @Gothmog,
    Could you provide your transceivers speed? VPN100 only support 1 Gigabit SFP. It won't work if plug in 10G SFP+.
    Please kindly refer the following datasheet. 

    Thank you
    Kevin

    could you point me at the correct 1GB version of the same? I have no clue about wavelength. This one is the working one when I use the router in between: Zyxel PM7000-00 XGSPON SFP+ Type SFU 

    Thanks!

    Hi @Gothmog,
    "PM7000-00 XGSPON SFP+ Type SFU " is SC connector.However, we only support LC connector.
    You may change your fiber cable to Duplex LC and find the tranceiver with single mode . 
    According to PM7000-00 XGSPON datasheet, I'll advice pick SPF-LHX1310-40D-D but please notice we can't ensure that ISP is compatible with 1G SFP. 
    Thank you
    Kevin

    Hi @Gothmog,
    Please be ware the different of active fiber (usually connect to Ethernet switch) and passive fiber (usually connect to PON).

    All the transceivers in Firewall support list is for active fiber.
    It won't work if you want to connect to PON.

    What's you need is a GPON ONU module. But cannot find the compatibility list for Zyxel firewall.
