Product Overview
The Cisco ® Dense Wavelength-Division Multiplexing (DWDM) X2 pluggable module (Figure 1) allows enterprise companies and service providers to offer scalable and easy-to-deploy 10 Gigabit Ethernet services in their networks.
Figure 1. Cisco DWDM X2 Module
Main features of the Cisco DWDM X2 include:
• The Cisco DWDM X2 supports 10GBASE Ethernet.
• The hot-swappable input/output device plugs into an Ethernet X2 port of a Cisco switch or router to link the port with the network.
• The Cisco DWDM X2 supports the Cisco Quality Identification (ID) feature, which enables a Cisco switch or router to identify whether or not the module is an X2 module certified and tested by Cisco.
• The module supports 32 nontunable ITU 100-GHz wavelengths compatible with the Cisco ONS DWDM channel plan.
• The Cisco DWDM X2 supports digital optical monitoring capability.
Platform Support
The Cisco DWDM X2 is supported across a variety of Cisco switches, routers, and optical transport devices. For more details, refer to the Cisco wavelength-division multiplexing transceivers compatibility matrix at
Connectors and Cabling
• Equipment: Standard X2 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.
Dimensions
Dimensions (D x W x H) are 91 x 36 x 13.46 mm. Cisco X2s typically weigh less than 300 grams.
Environmental Conditions and Power Requirements
• Operating temperature range: 32 to 158°F (0 to 70°C)
• Storage temperature range: -40 to 185°F (-40 to 85°C)
The maximum power consumption per Cisco X2 module is 4W.

Notes:
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. 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.
Warranty
The standard warranty is 90 days.
