An SFP port (Small Form-factor Pluggable) is a compact, hot-swappable interface used in network switches, routers, and firewalls to support fiber optic or copper networking cables. It enables networks to adapt to different speeds, media types, and distances without replacing. Majority of the switch ports in AI back-end Networks to be 800 Gbps in 2025 and 1600 Gbps in 2027, showing a very fast migration to the highest speeds available in the market. These challenges are forcing innovation to happen at all levels, including pluggable modules. The wide variety of modules gives you flexible and cost-effective options for all types of interfaces. Well. An SFP28 port can use a 25G SFP28 optical module or 10G SFP+ optical module.
