The small form-factor pluggable refers to the compact and hot-pluggable network interface, ideal for both data communications and telecommunication applications. The SFP interface available on the networking hardware is the modular slot ideal for the media-specific transceiver that can connect a copper cable or fibre-optic cable. So, SFP transceivers act as the primary workhorse in multiple networks. The small size allows it to be extensively used in tight networking spaces meant for fast communication between the switches and other essential networking components. Available in various options, the SFP transceiver is hot-swappable, making it perfect for adjusting or expanding existing networks with no redesigning required.
