Product Overview

The Cisco ® 10GBASE X2 modules (Figure 1) offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

Figure 1. Cisco 10GBASE X2 and Xenpak Modules

Main features of Cisco 10GBASE X2 modules include:

• Support 10GBASE Ethernet

• Hot-swappable input/output device plugs into an Ethernet X2 port of a Cisco switch or router to link the port with the network

• Provides flexibility of interface choice

• Supports "pay-as-you-populate" model

• Supports the Cisco quality identification (ID) feature that enables a Cisco switch or router to identify whether the module is certified and tested by Cisco

• Has optical interoperability with respective 10GBASE Xenpak, 10GBASE XFP and 10GBASE SFP+ modules on the same link

Cisco X2-10GB-CX4

The Cisco 10GBASE-CX4 Module supports link lengths of up to 15m on CX4 cable.

Cisco X2-10GB-T

The Cisco 10GBASE-T Module supports link lengths of up to 100m on CAT6A or CAT7 copper cable.

Cisco X2-10GB-LRM

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: http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html.
The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard single-mode fiber (SMF, G.652).

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. For additional information on mode conditioning patch cord requirements please see: http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html.

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

Cisco X2-10GB-ZR

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

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, -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.

Table 1 provides cabling specifications for the Cisco X2 modules.
