A Small Form-factor Pluggable (SFP)module is a compact, hot-swappable device used in networking equipment to transmit and receive data over fiber optic or copper cables. It combines both transmitting and receiving functions into one modular unit, enabling flexible network configurations. These transceivers are commonly used in switches, routers, and other network devices with compatible ports. Designed for scalability and efficient data transfer, they support various data rates, communication protocols, and distances, making them a reliable component in modern network systems.
