The Cisco® 10GBASE Dense Wavelength-Division Multiplexing (DWDM) SFP+ Modules (Figure 1) allow

enterprises and service providers to provide scalable and easy-to-deploy 10-Gigabit LAN, WAN, and optical transport network (OTN) services in their networks

The Cisco DWDM SFP+ 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 SFP+ port of a Cisco switch or router to link

- the port with the network.

- The Cisco DWDM SFP+ 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.

- The standard Cisco DWDM SFP+ supports 40 non-tunable ITU 100-GHz wavelengths.

- Cisco DWDM SFP+ modules support digital optical monitoring capability.
