1000BASE-CWDM SFP Transceiver Cables

The Coarse Wavelength Division Multiplexing (CWDM) SFP transceivers are hot-swappable
transceivers that you plug into SFP-compatible I/O modules. The CWDM SFP transceiver uses an LC
optical connector to connect to single-mode fiber-optic (SMF) cable. You can connect the CWDM SFPs
to CWDM passive optical system optical add/drop multiplexer (OADM) modules or
multiplexer/demultiplexer plug-in modules using SMF cables. CWDM SFP transceivers can transmit
and receive optical signals up to 61 miles (100 km) depending on the quality of the fiber-optic cable used.
CWDM SFP transceivers are color coded to indicate their designated optical wavelength.
shows the CWDM transceiver, which looks like a standard 1000BASE-X SFP transceiver with a colored
arrow and bail clasp to indicate the designated wavelength.
Whenever the transceiver receive optical bores are not filled with optical cables, you should minimize
Note
the chance of contamination by plugging the transceiver with its dust plug.
