Figure 1. Cisco 10GBASE SFP+ Modules
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 digital optical monitoring capability
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-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: https://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 FET-10G
The Cisco FET-10G Fabric Extender Transceiver support link lengths up to 100m on laser-optimized OM3 multimode fiber. It is supported on fabric links only from a Nexus 2000 to a Cisco parent switch. Note this product is not orderable individually. For more information refer to Nexus 2000 datasheet: https://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps10110/data_sheet_c78-507093.html.
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-10G-ER
The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard single-mode fiber (SMF,G.652).
Cisco SFP+ Copper
Cisco SFP+ Copper Twinax cables are suitable for very short distances and offer a highly cost-effective way to connect within racks and across adjacent racks. Cisco offers passive Twinax cables in lengths of 1, 3 and 5 meters, and active Twinax cables in lengths of 7 and 10 meters.
Technical Specifications
Platform Support
Cisco SFP+ modules are supported on Cisco switches and routers. For more details, refer to the document "Cisco 10 Gigabit Ethernet Transceiver Modules Compatibility Matrix": https://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.html.
Connectors and Cabling
Connectors: Dual LC/PC connector (-SR, -LRM, -LR, -ER, and FET-10G)
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.
