Features and Benefits
Main features of Cisco 10GBASE SFP+ modules include:
• Smallest 10G form factor
• Supports 10GBASE Ethernet
• Hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch
• Provides flexibility of interface choice
• Supports "pay-as-you-populate" model
• Supports the Cisco quality identification (ID) feature that enables a Cisco switch to identify whether the module is certified and tested by Cisco
• Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link
Cisco SFP-10G-SR
The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF (OM3), up to 300m link lengths are possible.
Cisco SFP-10G-LR
The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652)
Cisco SFP+ Copper
Cisco SFP+ Copper Twinax cables are suitable for very short distances of up to 10m. Twinax cables offer a highly cost-effective way to connect within racks and across adjacent racks.
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.
