Features and Benefits
Main features of Cisco 10GBASE SFP+ modules include:
sfp-10g-lr 光模块
• Smallest 10G form factor
• Supports 10GBASE Ethernet
sfp-10g-lr 光模块
• 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
sfp-10g-lr 光模块
• 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
sfp-10g-lr 光模块
• Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link
Cisco SFP-10G-SR
sfp-10g-lr 光模块
The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.
Cisco SFP-10G-SR-X
sfp-10g-lr 光模块
The Cisco SFP-10G-SR-X is a 10GBASE-SR module for extended operating temperature range. It supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m 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 or OM4. 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 FET-10G
sfp-10g-lr 光模块
The Cisco FET-10G Fabric Extender Transceiver support link lengths up to 100m on laser-optimized OM3 or OM4 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:http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps10110/data_sheet_c78-507093.html
Cisco SFP-10G-LR
sfp-10g-lr 光模块
The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652).
Cisco SFP-10G-LR-X
sfp-10g-lr 光模块
The Cisco SFP-10G-LR-X is a multirate 10GBASE-LR, 10GBASE-LW and OTU2e module for extended operating temperature range. It 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-10G-ZR
The Cisco 10GBASE-ZR Module supports link lengths of up to about 80 kilometers on standard single-mode fiber (SMF, G.652). This interface is not specified as part of the 10 Gigabit Ethernet standard and is instead built according to Cisco specifications.
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":http://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, -ZR 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.
