SFP

SFP (Small Form-factor Pluggable) is a compact, hot-swappable device used in network equipment like switches and routers to connect various types of fiber optic or Ethernet cables. It allows network administrators to easily upgrade, change, or adapt connections without shutting down the entire system. Essentially, an SFP acts as a modular interface that can be inserted or removed as needed, providing flexibility for different communication standards and distances. This versatility makes SFPs a common choice for managing and expanding network infrastructure efficiently.
