Connecting the CWDM Passive Optical System to Your System
Connecting Cables to the CWDM 8-Channel Multiplexer/Demultiplexer Module
Note Make sure that the CWDM GBIC transceiver color code or CWDM SFP transceiver color code matches
the color code of the OADM port to which it is connected.
To connect cables to a CWDM 8-channel multiplexer/demultiplexer module, follow these steps (see
Figure 19):
Step 1 Insert the CWDM GBIC or CWDM SFP transceivers into the appropriate modules on your switch or
router system if you have not already done so. For more information on installing CWDM GBIC
transceivers and SFP transceivers, refer to the Cisco CWDM GBIC and CWDM SFP Installation Note.
Note Clean all fiber-optic plugs on the cables before inserting the plugs into the fiber-optic
connectors.
Note Always use single-mode fiber-optic patch cables to connect the 8-channel
multiplexer/demultiplexer ports to the CWDM GBIC transceivers and CWDM SFP transceivers.
Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not view directly with optical instruments. Viewing the laser output with certain optical instruments
(for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye
hazard.
