10-Gigabit X2 Transceivers
10BASE-DWDM SFP+ Transceivers
The Dense Wavelength Division Multiplexing (DWDM) SFP+ transceivers are part of a DWDM optical
network to provide high-capacity bandwidth across a fiber-optic network. There are 32 fixed-wavelength
DWDM SFP+ transceivers that support the International Telecommunications Union (ITU) 100-GHz
wavelength grid. These transceivers have duplex SC connectors. DWDM SFP+ transceivers can transmit
and receive optical signals up to 50 miles (80 km) depending on the quality of the fiber-optic cable used.
DWDM SFP+ transceivers look like the typical 10GBASE-X SFP+ transceivers as shown in Figure B-4
on page B-8.
For the specifications that differentiate the 10GBASE-DWDM SFP+ transceivers, see the 10-Gigabit
Ethernet Transceiver Modules Compatibility Matrix.
10-Gigabit X2 Transceivers
The following 10-Gigabit X2 transceivers are used with the 8-port 10-GB Ethernet (N7K-M108X2-12L)
I/O modules:
• DWDM-X2-xx.xx
• X2-10GB-CX4
• X2-10GB-ER
• X2-10GB-LR
• X2-10GB-LRM
• X2-10GB-LX4
• X2-10GB-SR
• X2-10GB-ZR
Additionally, you can use the following SFP+ transceivers with the OneX Converter Module (part
number CVR-X2-SFP10G) that adapts SFP+ transceivers to X2 ports:
• SFP-10G-SR
• SFP-H10GB-CUxM
For information on the SFP+ 10GB transceivers, see the “10-Gigabit SFP+ Transceivers and Fabric
Extender Transceivers” section on page B-6.
Figure B-5 identifies the major features of the X2 transceivers, and Figure B-6 shows the transceiver
with its latching sleeve extended (you pull the sleeve out to remove the transceiver from the I/O module).
