The Cisco 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface 

(FDDI) grade multimode fiber (MMF). To ensure that specifications are met over FDDI-grade, OM1 and OM2 fibers, 

the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is 

required for applications over OM3. For additional information on mode conditioning patch cord requirements 

please see: 

. 

The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard single-mode fiber (SMF, G.652). 

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. For 

additional information on mode conditioning patch cord requirements please see: 

. 

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. Using 4700 MHz*km MMF (OM4), up to 400m link lengths are 

possible. 

The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, 

G.652). 

The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard single-mode fiber (SMF, 

G.652). 

Supports link lengths of up to about 80 km on SMF. This interface is not part of the 10 Gigabit Ethernet standard 

but is built according to Cisco optical specifications. 

Technical Specifications 

Cisco X2 modules are supported on Cisco switches and routers. For more details, refer to the document Cisco 

Xenpak/X2 Compatibility Matrix. 

Connectors: Dual SC/PC connector (-SR, -LR, -LRM, -LX4, -ER, -ZR); InfiniBand 4x connector (-CX4); RJ-45 

connector (-T). 

Note:   For optical X2 modules, 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.
