Product Overview

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

Figure 1. Cisco 10GBASE XENPAK Modules

Main features of Cisco 10GBASE XENPAK modules include:

Supports 10GBASE Ethernet

Hot-swappable input/output device plugs into an Ethernet XENPAK 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 feature that enables a Cisco switch or router to identify whether the module is a Cisco certified and tested XENPAK module

Interoperable with respective Cisco 10-Gigabit X2, XFP and SFP+ modules on the same link

Cisco offers six modules in this product family:

Cisco XENPAK-10GB-CX4: Supports link lengths of up to 15m on CX4 cable.

Cisco XENPAK-10GB-LRM: Supports link lengths 220m on standard 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 XENPAK-10GB-SR: Supports a link length of 26m on standard FDDI grade MMF. Up to 300m link lengths are possible when using 2000 MHz/km MMF (OM3). Up to 400m link lengths are possible when using 4700 MHz/km MMF (OM4).

Cisco XENPAK-10GB-LR+: Supports a link length of 10 km on standard single-mode fiber (SMF) (G.652).

Cisco XENPAK-10GB-ER+: Supports a link length of up to 40 km on SMF (G.652).

Cisco XENPAK-10GB-ZR: Supports link lengths of up to about 80 km on SMF. This interface is not part of the 10 Gigabyte Ethernet standard but is built according to Cisco optical specifications.

Technical Specifications

Platform Support

Cisco XENPAK modules are supported on Cisco switches and routers. For more details, refer to the 10-Gigabit compatibility matrix: http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.pdf

Connectors and Cabling

Connectors:

XENPAK-10GB-CX4: InfiniBand 4x connector

All others: Dual SC/PC connector

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.

* Minimum cabling distance for optical XENPAK modules (-LX4, -SR, -LR, -ER) is 2m, according to the IEEE 802.3ae standard, and minimum cabling distance for -LRM modules is 0.5m, according to IEEE 802.3aq standard.
** Data based on standard G.652 SMF. Even though dispersion-shifted fiber enables reducing signal dispersion to travel longer distances, the signal attenuation still limits its distance.
*** Requires 5 dB 1550 nm fixed loss attenuator for < 20 km. Attenuator is available as a spare. The part number is WS-X6K-5DB-ATT=.
**** Links longer than 30 km are considered engineered links.

Table 2 shows the main optical characteristics for the Cisco XENPAK modules. The Cisco XENPAK-10GB-CX4 is not an optical module and therefore is not listed in the table.
