Small Form-factor Pluggable

OverviewSFP typesQSFPApplicationsStandardizationMechanical dimensionsDigital diagnostics monitoring

Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper cable. The advantage of using SFPs compared to fixed interfaces (e.g. modular connectors in Ethernet switches) is t
