What are the advantages of a small pluggable (SFP) port of a Gigabit Ethernet switch? How to connect four SFP ports of a D-link DGS 1248 T smart switch?
I think the main advantage of SFP ports is the flexibility to connect to the network. The SFP port is a hot pluggable input/output device that can be plugged into a Gigabit Ethernet port or slot to connect this port to the network. The SFP port can be used on many products and can be interchanged with 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX or 1000BASE-BX10-D/U and other products. SFP ports are available for Gigabit Ethernet and Fibre Channel. They can provide a flexible and cost-saving solution for enterprise networks, data centers, and more.
To connect a D-link switch, you need to purchase the appropriate SFP module. It should have fiber optic connections to and from the remote network. These ports are sold separately and you need to purchase them separately from local manufacturers.
