sfp might be an issue for my since my modem and Ap don’t have that port
SFP is something like a port for ports - you buy an SFP module based on what port you need, so you can just buy a network device with SFP cages that can handle your required speed and then pick a combination of Ethernet / optical SFP modules that match your needs. But the modules aren’t exactly cheap, even the Ethernet ones.
