The Cisco® Dense Wavelength-Division Multiplexing (DWDM) XFP pluggable module (Figure 1) allows enterprise companies and service providers to provide scalable and easy-to-deploy 10 Gigabit LAN, WAN, and Optical Transport Network (OTN) services in their networks.
Figure 1. Cisco DWDM XFP Module
Main features of the Cisco DWDM XFP include:
• The Cisco DWDM XFP supports 10-Gigabit data rates from 9.9G to 11.1G (LAN, WAN, and OTU2/OTU2e).
• The hot-swappable input/output device plugs into an Ethernet XFP port of a Cisco switch or router to link the port with the network.
• The Cisco DWDM XFP supports the Cisco quality identification (ID) feature, which enables a Cisco switch or router to identify whether or not the module is an XFP module certified and tested by Cisco.
• The standard Cisco DWDM XFP supports 32 nontunable ITU 100-GHz wavelengths.
• The tunable Cisco DWDM XFP supports 80 tunable ITU 50-GHz wavelengths.
• Cisco DWDM XFP modules supports digital optical monitoring capability.
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 (L x W x H): 71 x 18.5 x 8.5 mm. Cisco XFPs 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 XFP module is 3.5W.
