Optical modules compliant with the SFP (Small Form-factor Pluggable) standard are devices that convert electrical signals to optical and optical signals to electrical.

Using media converters with interchangeable SFP modules is particularly beneficial, as they provide versatility. In case of network configuration changes, instead of replacing the entire device or adding new media converters, it is enough to choose the appropriate SFP module.

The modules are compatible with most switches and routers with an SFP socket.
