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 a 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. The following figure
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.

1 Colored arrow on label specifies the wavelength
2 Receive optical bore
3 Transmit optical bore
Whenever the transceiver receive optical bores are not filled with optical cables, you should minimize the
chance of contamination by plugging the transceiver with its dust plug.
For the Cisco CWDM SFP transceiver cable specifications, see the following table.
