The small form-factor pluggable (SFP) is a compact, hot-pluggable network interface module used for both
telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot
for a media-specific transceiver in order to connect a fiber-optic cable or sometimes a copper cable.
The advantage of using SFPs compared to fixed interfaces (e.g. modular connectors in Ethernet switches) is that
individual ports can be equipped with any suitable type of transceiver as needed.
