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.
● 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.
● 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.
