DATA SHEET

OVERVIEW

The Cisco ® Dense Wavelength-Division Multiplexing (DWDM) XENPAK pluggable allows enterprise companies and service providers to provide scalable and easy-to-deploy 10 Gigabit Ethernet services in their networks (Figure 1).
Main features of the Cisco DWDM XENPAK include:

• The Cisco DWDM XENPAK supports 10GBASE Ethernet.

• The hot-swappable input/output device plugs into an Ethernet XENPAK port of a Cisco switch or router to link the port with the network.

• The Cisco DWDM XENPAK supports the Cisco quality identification (ID) feature that enables a Cisco Systems® switch or router to identify whether or not the module is a Cisco certified and tested XENPAK module.

• The Cisco DWDM XENPAK supports 32 non-tunable ITU 100 GHz wavelengths compatible with the Cisco ONS DWDM channel plan.

• The Cisco DWDM XENPAK supports digital optical monitoring capability.

PLATFORM SUPPORT

The Cisco DWDM XENPAKs are supported across a variety of Cisco switches, routers, and optical transport devices. For more details, refer to the document Cisco DWDM XENPAK Compatibility Matrix.

Connectors and Cabling

• Equipment: Standard XENPAK interface

Network: Dual SC/PC connector

Note: Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section.

Dimension:

Cisco DWDM Xenpak's typically weighs less than 300 grams

Environmental Conditions and Power Requirements

• Operating temperature range: 32 to 122°F (0 to 55°C)

• Storage temperature range: -40 to 185°F (-40 to 85°C)

The maximum power consumption per Cisco XENPAK is 8W.

Note: 1. Parameters are specified over temperature and at end of life unless otherwise noted.
2. When shorter distances of single-mode fiber are used, an inline optical attenuator (10-dB) must be used to avoid overloading and damaging the receiver.
3. The receive-only WDM XENPAK has no transmitter. The receiver matches the receiver specifications given above.
4. To prevent burst errors, Cisco suggests the use of appropriate optical attenuation in front of the receiver when interoperating X2 DWDM and XENPAK DWDM specifically under the following conditions:
- When the input power on the receiver exceeds -14dBm,
- When the optical signal to noise ratio is less than 30dB @ 0.1nm RBW
- When total chromatic dispersion is greater than 1500ps/nm
The attenuation should be chosen to limit the input power into the receiver to be less than -14dBm.
