Small Form-factor Pluggable (SFP) transceiver module is a compact and hot-swappable device used in networking equipment to transmit and receive data over fiber optic or copper cables. It combines the functions of a transmitter and receiver into a single module, allowing for flexible and modular network configurations. SFP transceiver modules are commonly used in switches, routers, and other networking devices that have SFP ports. They provide the capability to connect different types of network media by simply plugging in the appropriate SFP module. SFP transceivers support various data rates, protocols, and distances, and can be easily swapped or upgraded without disrupting the network infrastructure. They offer flexibility, scalability, and efficient data transmission in network deployments.
