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 http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6982.html.

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.
