The industry-standard Cisco Small Form-Factor Pluggable (SFP) Gigabit interface converter is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network.
1000BASE-LX/LH SFP is designed for long-reach single-mode fibres but works over multi-mode fibre as well.
Operates on standard single-mode fibre-optic link spans of up to 10 km and up to 550 metres on multi-mode fibre (transmitter should be coupled through a mode conditioning patch cable when used over multi-mode fibre type)
Plugs into an Ethernet SFP port or slot with no need to shut down if installing or replacing
SFP receiver/transceiver module supports 'pay-as-you-populate' model for flexible media and interface choice on a port-by-port basis
