Currently no Omada Router supports 2.5 Gbps WAN port.

However if you are not in urgent, you may take a look at ER8411, it's not delivered yet(anyway I can't see anywhere I can purchase it), and this router supports 10G WAN port.

But some people said it could be very expensive.

 Fiber optic Internet is the future of broadband. It uses fiber-optic technology to reach the fastest speeds available today, as fast as 1000 Mbps (1Gpbs). Broadband is essential to the modern world we live in. Powered by fiber optic technology, fiber Internet is blowing its competitors out of the water. In this guide, we will cover everything you need to know about fiber Internet, including how it works and the challenges associated with it.

Hey there! I can definitely understand your concern regarding distributing 3 GBS Fibe bandwidth with your current setup. It's great that you have a basic setup with ER605, OC200, and the SG1008P switch, along with the EAP245 and EAP670 access points. However, I can see why you're worried about the bottleneck at the router and the limitation of Gigabyte ports. If you're considering upgrading to 3 GBS Fibe, it might be worth upgrading your router as well to ensure that you're able to distribute that much bandwidth efficiently. While the EAP670 has a 2.5GB port, it won't be of much use if your router is unable to handle that much bandwidth. In terms of the ER605, it does provide some additional security features, but you could still achieve a secure setup with just a switch by implementing VLANs and ensuring that each device is separated onto its own network. As for my own setup, I have a similar setup with the EAP245 and EAP330 access points, a UniFi switch, and a Ubiquiti EdgeRouter Lite router. While my setup isn't exactly the same as yours, I have found that the EdgeRouter Lite router is capable of handling high-speed internet connections without any issue. I hope this helps, and best of luck in your journey to learn the ropes of networking and Tech issues!
