Cisco X2-10GB-LX4
The Cisco 10GBASE-LX4 Module supports link lengths of 300m on standard FDDI grade MMF. To
ensure that specifications are met, the transmitter output should be coupled through a mode
conditioning patch cord.
Cisco X2-10GB-SR
The Cisco 10GBASE-SR Module supports a link length of 26m on standard FDDI grade MMF.
Using 2000 MHz*km MMF (OM3), up to 300m link lengths are possible.
Cisco X2-10GB-LR
The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode
fiber (SMF, G.652).
Cisco X2-10GB-ER
The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard single-
mode fiber (SMF, G.652).
Technical Specifications
Platform Support
Cisco X2 modules are supported on Cisco switches and routers. For more details, refer to the
document Cisco Xenpak/X2 Compatibility Matrix.
Connectors and Cabling
Connectors: Dual SC/PC connector (-SR, -LR, -LX4, -ER); InfiniBand 4x connector (-CX4)
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.
