Connecting the CWDM Passive Optical System to Your System
Connecting the CWDM Passive Optical System to Your System
This section is divided into the following topics:
• Connecting Cables to the Dual Single-Channel OADM Module, page 18
• Connecting Cables to the CWDM 4-Channel OADM Module, page 20
• Connecting Cables to the CWDM 8-Channel Multiplexer/Demultiplexer Module, page 23
Note Use the CWDM passive optical system connector color codes shown in Table 2 to help you connect the
CWDM passive optical system to your system.
See Figure 2 through Figure 13 for the OADM and multiplexer/demultiplexer module front panels.
Warning
Class 1M laser radiation when open. Do not view directly with optical instruments.
Statement 1053
Connecting Cables to the Dual Single-Channel OADM Module
Note Make sure that the CWDM GBIC or CWDM SFP transceiver color code matches the color of the OADM
port to which it is connected.
To connect the cables to the dual single-channel OADM module, follow these steps (see Figure 17):
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 CWDM SFP and CWDM GBIC
GBIC transceivers, refer to the Cisco CWDM GBIC and CWDM SFP Installation Note that accompanied
your transceivers.
Note Always use single-mode fiber-optic patch cables to connect dual single-channel OADM ports to
the CWDM GBIC or the CWDM SFP transceivers.
Note CWDM GBIC transceivers are equipped with SC connectors. To make connections to the LC
connectors on the OADM modules, you must use an LC to SC patch cable (Cisco part number
CAB-SM-LCSC-1M= [1 meter cable], CAB-SM-=LCSC-5M= [5 meter cable], or an equivalent
patch cable).
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.
