The Cisco 10GBASE DWDM SFP+ Modules are fiber line cards for a wide variety of Cisco switches, routers, and other equipment. They allow enterprises and service providers to provide scalable and easy-to-deploy 10-Gbps LAN, WAN, and optical transport network (OTN) services in their networks.

The Cisco 10GBASE Dense Wavelength-Division Multiplexing SFP+ Module offer the following features and benefits:

- Supports 10-Gigabit data rates from 9.9G to 11.1G (LAN, WAN, and OTU2/OTU2e) to accommodate different applications
- Smallest SFP+ module footprint in the industry
- Hot-swappable input/output device plugs into an Ethernet SFP+ port of a Cisco switch or router to link the port with the network
- Support for a “pay-as-you-grow” model for investment protection
- Digital optical monitoring capability for enhanced diagnostics and troubleshooting
- DWDM fixed module supports 40 non-tunable ITU 100-GHz wavelengths
- DWDM tunable module supports 96 tunable ITU 50-GHz wavelengths
- Supports the Cisco quality identification (ID) feature, which enables a Cisco switch or router to identify whether or not the module is an SFP+ module certified and tested by Cisco
