SFP

SFP stands for "Small Form-factor Pluggable." It's a compact, hot-pluggable transceiver module used in networking equipment to provide interfaces for various types of optical and electrical communication standards. SFP modules are commonly used in switches, routers, and other networking devices to enable flexible connectivity through interchangeable modules, supporting different data rates, distances, and types of connections, such as fiber-optic or copper Ethernet.
