Installation Note for the CWDM Passive Optical System
78-14167-01
Overview
Overview
The CWDM passive optical system provides optical networking support for high-speed data
communication for metropolitan area networks (MANs) over a grid of eight CWDM optical
wavelengths in both ring or point-to-point configurations.

You connect your multiplexed/demultiplexed wavelengths and added/dropped channels to CWDM
GBICs installed in your network switches.
GBICs installed in your network switches.
The CWDM passive optical system includes the following components:
•
CWDM system shelf
•
CWDM plug-in modules
•
CWDM GBICs
You install your CWDM OADM and multiplexer/demultiplexer (Mux/Demux) plug-in modules in your
CWDM system shelf. Install CWDM GBICs in your Catalyst 4000 and 6000 family switches to connect
them to your plug-in modules. A CWDM GBIC is a hot-swappable input/output device that links your
switching module to the CWDM passive optical system using a pair of single-mode fiber-optic cables.

CWDM System Shelf
The CWDM system shelf (CWDM-CHASSIS-2) is a standard 19-inch chassis that is one rack unit (RU)
in height. Install the CWDM system shelf in the same equipment rack as your switch or in an adjacent
rack so that you can connect the CWDM plug-in modules to the CWDM GBICs in your switch.

The CWDM system shelf has two slots. You install CWDM OADM modules or Mux/Demux plug-in
modules in the slots.

The CWDM OADM is a scalable passive optical multiplexer/demultiplexer that adds or drops two
CWDM channels of the same wavelength from network traffic and allows all other wavelengths to pass
straight through. The CWDM OADM maps each of the two added/ dropped channels into separate
single pair fiber paths traveling in opposite directions:”east” and “west.”

The CWDM Mux/Demux plug-in modules multiplex and demultiplex four or eight CWDM channels
(wavelengths) from a single-mode fiber-optic cable. The four-channel CWDM Mux/Demux module
passes straight through four of the eight wavelengths. You can create point-to-point, hub-and-spoke, and
ring networks using the CWDM Mux/Demux plug-in modules. Connect your CWDM Mux/Demux
plug-in module to CWDM GBICs of equivalent wavelengths that are installed in your switches.

Figure 1 shows the front panel of the CWDM four-channel Mux/Demux plug-in module.. Figure 2
shows the CWDM eight-channel Mux/Demux plug-in module. Figure 3 through 10 show the plug-in
modules for each of the available longwave spectrums. The plug-in module ports are color-coded to help
with installation. Each of the colors indicates the wavelength of the port. For more information about
the color codes, see the “Connecting the CWDM Passive Optical System to Your Switch” section on
