The term SFP stands for Small Form-factor Pluggable. A Fiber SFP module is a compact, hot-swappable device used to connect network equipment like switches, routers, and servers to fiber optic cables for data transmission.
Unlike traditional fixed interfaces, SFP modules offer the flexibility to choose the appropriate transceiver based on network requirements — such as transmission distance, data speed, and type of fiber (single-mode or multi-mode).
One of the most valuable aspects of SFP modules is their hot-swappable design. This means you can insert or replace them without having to power down the device, making them ideal for minimizing downtime during upgrades or maintenance.
