Cisco CWDM SFP - SFP (mini-GBIC) transceiver module - 1GbE, 2Gb Fibre Channel

The CWDM SFPs are hot-swappable, transceiver components that you can plug into standard receptacles in Cisco routers and switches and convert Gigabit Ethernet electrical signals into a single-mode fiber-optic (SMF) interface. You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables with standard SC connectors.
