What is the advantage of SFP ports on a Gigabit switch?
Our routing and switching expert explains the benefits of SFPs on a Gigabit
Ethernet switch. SFP stands for "small form-factor pluggable" and is a hot-swappable
input/output device that plugs into a switch port, allowing multiple options for connectivity.
QUESTION: What is the advantage of SFP ports
on a Gigabit switch? And how do I connect the four SFP ports on a D-link DGS 1248 T smart
The main advantage that I see for the SFP is the flexibility it gives you for putting it in
the network. SFP stands for "small form-factor pluggable" and is a hot-swappable input/output
device that plugs into a Gigabit
port or slot, linking the port with the network. SFPs can be used and interchanged on
a wide variety of products and can be interchanged in combinations of 1000BASE-SX, 1000BASE-LX/LH,
1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis. You can use them for Gigabit Ethernet or
. They provide a flexible and cost-effective solution for enterprise
networks, data centers, etc.
To connect to a D-link, you need to buy appropriate SFP modules for the same. It should have
fiber connectivity from/to remote network. These ports are sold separately from your local
