Hello, I have a few questions for you. Can a GPON connection be made with the Keenetic SFP port? In my area, Huawei ONT and OLT are used, and verification is done with the SN number. Another question: does Keenetic have a product with a 10G SFP port (I couldn't find one in my country)? Also, if I connect a 10G SFP to a Keenetic 1G SFP port, will the connection be established? Additionally, does Cisco support SFP?
