Currently, I have a mobile PON dedicated line at home, with a B610-s1-4e 1 port configured for my dedicated line. When I look at the fiber ONU, I don't see any VLAN configurations or other information, which gives the impression of a simple optical-electrical converter. I'm now wondering if it's possible to configure two ports for a separate mobile broadband connection. In the context of OLT-based networking, is this a technically feasible idea? Would I need to perform additional VLAN configurations or utilize a different type of terminal equipment for successful implementation? I would appreciate any guidance on this matter.
