Thanks. &nbsp;I will look into the video soon <br />
So it looks like the SFP is not for stacking switches, it is for fibre connections.

That is correct. Stacking switches typically use dedicated,propriety ports for the stacking connections.

I will get my first smart gigabit network switch soon. I am looking at D-Link DGS-1210-52 and DGS-1510-52. I am not sure which one to buy as I am not very clear what the SFP ports for?<br />
Are they for linking to another switch? I may get the 2nd smart switch too. <br />
Anyone would be able to shed me some light?<br />
Thanks!!

What is SFP port for?

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
