What is an SFP module? Pretty sure it’s not Super Fuckin Pretty
gpt
its smal form-factor pluggable. it is a modular slot for an interface used by switches, routers, firewalls, servers and so on. you can plugin a transceiver (module, which transmits and receives data) in a sfp slot. the transceivers can be laser, light (used with fibre optic cables) or also copper (rj45, your common LAN cable). that way you can connect devices narrow or far (up to 10km or more) and at different bandwidth (up to 100Gbit/s or more) depending which transceiver you buy and cables you use.
