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.

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.
