Overview
The Cisco 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.
The Cisco CWDM passive optical system includes the following components:
•2-slot chassis for Cisco Optical Add/Drop Multiplexers (OADMs)
•CWDM OADMs
–Dual single-channel OADMs
–4-channel OADM
–8-channel multiplexer/demultiplexer
–Single fiber 4-channel multiplexer/demultiplexers
•CWDM GBICs
CWDM 2-Slot Chassis
The CWDM 2-slot chassis (CWDM-CHASSIS-2) is a standard 19-inch chassis that is one rack unit (RU) in height. Each CWDM 2-slot chassis can hold two CWDM OADM modules. You can install the CWDM 2-slot chassis in the same equipment rack as your system or in an adjacent rack so that you can connect the OADMs to the CWDM GBICs.
CWDM OADMs
The CWDM OADMs are passive devices that can multiplex/demultiplex or add/drop wavelengths from multiple fibers onto one optical fiber. The OADM connectors are interfaced to the color-matching CWDM GBICs on the equipment side. All the modules are the same size. The CWDM 2-slot chassis allows you to rack mount up to two CWDM OADMs in a single rack unit. There are four different types of CWDM OADMs:
•Dual Single-Channel OADMs (CWDM-MUX-AD-xxxx—Allows you to add/drop two channels of the same wavelength into the two directions of an optical ring. The other wavelengths are passed through the OADM. Dual fiber is used for both the network and the CWDM GBIC connections. Eight versions of this OADM are available, one for each wavelength of light. (See Table 1.) The dual single-channel OADMs are color coded and match the color coding of the CWDM GBICs.
•4-Channel OADM (CWDM-MUX-4=)—Allows you to add/drop four channels (with different wavelengths) into one direction of an optical ring. The other wavelengths are passed through the OADM. Dual fiber is used for both the network and the GBIC connections. The four wavelengths are set to 1470 nm, 1510 nm, 1550 nm, and 1590 nm.
•8-Channel Multiplexer/Demultiplexer (CWDM-MUX-8=)—Allows you to multiplex/demultiplex eight separate channels into one pair of fiber. Dual fiber is used for both the network and the GBIC connections. The eight available wavelengths are 1470 nm, 1490 nm, 1510 nm, 15300 nm, 1550 nm, 1570 nm, 1590 nm, and 1610 nm.
•Single-Fiber 4-Channel Multiplexer/Demultiplexer (CWDM-MUX-4-SFx=)—Allows you to multiplex/demultiplex four separate channels into one strand of fiber. Dual fiber is used for the connections to the GBICs and single fiber is used for the network connections. The two models (CWDM-MUX-4-SF1= and CWDM-MUX-4-SF2=) must be used together to create a four-channel single-fiber point-to-point link. This module uses the same CWDM GBICs as all of the other CWDM OADMs.
See Table 2 for a comparison of the CWDM passive device types.
Figure 1 shows the front panel of the CWDM 4-channel OADM module. Figure 2 shows the CWDM 8-channel multiplexer/demultiplexer module. Figures 3 through 10 show the dual single-channel OADM modules for each of the available wavelengths.
The OADM module ports are color coded to help with installation. Each color indicates the wavelength of the port. For more information about the color codes, see the "Connecting the CWDM Passive Optical System to Your System" section. Figure 11 and Figure 12 show the front panels of the CWDM 4-channel multiplexer/demultiplexer modules (CWDM-MUX-4-SF1 and CWDM-MUX-4-SF2).

CWDM GBICs
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. You can connect your multiplexed/demultiplexed wavelengths and added/dropped channels to CWDM GBICs that are installed in your system.
CWDM GBICs are available in eight wavelengths (see Table 3.) Each GBIC is color coded to match the connector colors on the OADM modules.
For information on installing, removing, and maintaining the CWDM GBICs, refer to the CWDM GBIC Installation Note that accompanies the CWDM GBICs.

Use the CWDM passive optical system connector color codes shown in Table 4 to help you connect the CWDM passive optical system to your system.
See Figure 1 through Figure 12 for the OADM and multiplexer/demultiplexer module front panels.
Warning Class 1M laser radiation when open. Do not view directly with optical instruments.
Connecting Cables to the Dual Single-Channel OADM Module
Note Make sure that the CWDM GBIC color 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 15):
Step 1 Insert the CWDM GBICs into the appropriate connectors on your switch/router system if you have not already done so. For more information on CWDM GBICs, refer to the CWDM GBIC Installation Note.
Note Always use single-mode fiber-optic patch cables to connect dual single-channel OADM ports to the CWDM GBICs.
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.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The avenue of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
Cisco TAC Website
You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC website, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
http://tools.cisco.com/RPF/register/register.do
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:
http://www.cisco.com/en/US/support/index.html
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC website so that you can describe the situation in your own words and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
