SFP stands for “small form-factor pluggable” and transceiver means a device that can both transmit and receive data. This article “SFP Transceivers Explained” is intended to describe all about SFP transceivers in detail that could help network professionals understand about SFP optics and its types.

The SFP transceiver is a compact, hot-swappable device that plugs into a physical port of a network device. SFP optics are used in communication networks and have a transmitting side (Tx) and a receiving side (Rx). The transceiver has a laser which communicates to the receiving side of the other optic on the other side.
