"An SFP interface on networking hardware is a modular (plug-and-play) slot for a media-specific transceiver in order to connect a fiber optic cable or sometimes a copper cable."
Just to clarify I guess this means that the "CRS305-1G-4S+IN: Five-port desktop switch with one Gigabit Ethernet port and 4 SFP+ 10Gbps ports" is a 4 port SPF+ switch, and it depends on the transceiver (not included) that you use, whether you connect using copper or optic fiber ?
