Connecting the EWDM Passive Optical System to Your System
Connect the single pair fiber-optic cables from the CWDM GBIC transceivers or CWDM SFP
Step 4
transceivers (Tx/Rx; up to eight channels) to the multiplexer/demultiplexer module equipment
connectors (Tx/Rx; up to eight wavelengths). An eight-channel, four-channel, or one-channel OADM or
Mux/demux may be used depending on your needs.
Note
Connect the single pair fiber-optic cables from the DWDM transceivers (Tx/Rx; up to eight channels) to
Step 5
the 8-channel multiplexer/demultiplexer module equipment connectors (Tx/Rx; up to eight
wavelengths).
Connect the NETWORK port on the CWDM passive module to the CWDM UPG port on the EWDM
Step 6
OADM module.
Step 7
Connect the network backbone single pair fiber-optic cable to the multiplexer/demultiplexer
NETWORK connector on the EWDM OADM module.
Step 8
Connect the AMP IN and AMP OUT ports of the EWDM module if you have not already done so.
Connecting Cables for a Boosted Application
Make sure that the CWDM GBIC transceiver color code or CWDM SFP transceiver color code matches
Note
the color code of the CWDM OADM port to which it is connected, and make sure that the DWDM
transceiver wavelength matches the wavelength label of the EWDM OADM port.
To connect cables for a boosted application, follow these steps (see
Insert the transceivers into the appropriate modules on your switch or router system if you have not
Step 1
already done so.
Note
Always use single-mode fiber-optic patch cables to connect the OADM ports to the transceivers.
Note
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
Warning
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. Statement 1056
Cisco Enhanced Wave Division Multiplexing Optical System Installation Note

Connect the Tx ports to the Rx ports and the Rx ports to the Tx ports to ensure that the system
operates correctly.
Clean all fiber-optic plugs on the cables before inserting the plugs into the fiber-optic
connectors.
