Hi, Thanks for your quick response.

According to the WAS-110 description. This is what I need:

• An XGSPON ONU SFP+ Module compatible with the 8311 firmware
• LC/APC to SC/APC cable
• A device with a spare SFP+ slot (ie switch, router etc)
•  

I have been following a guide at fttpprodotcodotuk    

The WAS-110 people have helped me and still are but  have no knowledge of the TP-Link kit, hence I thought someone in here may have done this.

I cannot use the setup up you have shown as the ER7212PC does not have an SFP+ slot only SFP. The WAS-110 needs SFP+. I did try it but although the port status changed I could not ping it or see it on the network.

Is there a way of plugging it into the switch and linking it to the ER7212PC?

To connect the WAS-110 and route its connection to the router’s WAN port through the same switch, the switch must be configured with separate VLANs for WAN and LAN traffic. The WAS-110 and the router’s WAN port are placed on a dedicated WAN VLAN, while the router’s LAN port and all PCs remain on a separate LAN VLAN.

High-Level Steps

1. Create a WAN VLAN on the switch.

2. Create a LAN VLAN on the switch.

3. Assign:

         WAS-110 → WAN VLAN (untagged)

        Router WAN port → WAN VLAN (untagged)

       Router LAN port → LAN VLAN (untagged)

       All PCs → LAN VLAN

4. Ensure no routing or bridging exists between VLANs on the switch.
