Features and Benefits
Cisco SFP+ modules offer the following features and benefits.
●
Industry’s smallest 10G form factor for greatest density per chassis
●
Hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch (no need to
power down if installing or replacing)
●
Supports “pay-as-you-populate” model for investment protection and ease of technology migration
●
Digital optical monitoring capability for strong diagnostic capabilities
●
Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same
link
●
Cisco quality identification (ID) feature enables a Cisco platform to identify whether the module is certified
and tested by Cisco
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 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
The Cisco SFP-10G-SR-X is a multirate* 10GBASE-SR, 10GBASE-SW and OTU2/OTU2e 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

Except for version 1, which supports only 10GBASE-SR
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 make sure 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
The Cisco FET-10G Fabric Extender Transceiver supports link lengths up to 100m on laser-optimized OM3 or OM4
multimode fiber. It is supported on fabric links from a Nexus 2000 to a Cisco parent switch only. 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
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
The Cisco SFP-10G-LR-X is a multirate 10GBASE-LR, 10GBASE-LW, and OTU2/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 SFP-10G-ZR is a multirate 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e module. It 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-10G-BXD-I and SFP-10G-BXU-I for 10Km (Single-Fiber Bidirectional Applications)
The Cisco SFP-10G-BXD-I and SFP-10G-BXU-I SFPs operate on a single strand of standard SMF.
A SFP-10G-BXD-I device is always connected to a SFP-10G-BXU-I device with a single strand of standard SMF
with an operating transmission range up to 10 km.
The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two
devices, as depicted in Figure 2. SFP-10G-BXD-I transmits a 1330-nm channel and receives a 1270-nm signal,
whereas SFP-10G-BXU-I transmits at a 1270-nm wavelength and receives a 1330-nm signal. Note in Figure 2 the
presence of a wavelength-division multiplexing (WDM) splitter integrated into the SFP to split the 1270-nm and
1330-nm light paths.
Figure 2. Bidirectional Transmission of a Single Strand of SMF
The SFP-10G-BXD-I and SFP-10G-BXU-I SFPs also support digital optical monitoring (DOM) functions according
to the industry-standard SFF-8472 multisource agreement (MSA). This feature gives the end user the ability to
monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias
current, and transceiver supply voltage.
Cisco SFP-10G-BX40D-I and SFP-10G-BX40U-I (for 40Km Single-Fiber Bidirectional
Applications)
The Cisco SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs operate on a single strand of standard SMF.
A SFP-10G-BX40D-I device is always connected to a SFP-10G-BX40U-I device with a single strand of standard
SMF with an operating transmission range up to 40 km.
The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two
devices. SFP-10G-BX40D-I transmits a 1330-nm channel and receives a 1270-nm signal. The SFP-10G-BX40U-I
transmits at a 1270-nm wavelength and receives a 1330-nm signal.
The SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs support digital optical monitoring (DOM) functions according
to the industry-standard SFF-8472 multisource agreement (MSA). This feature gives the end user the ability to
monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias
current, and transceiver supply voltage.
Cisco SFP+ Twinax Copper Cables
Cisco SFP+ Copper Twinax (Figure 3) direct-attach cables are suitable for very short distances and offer a costeffective way to connect within racks and across adjacent racks. Cisco offers passive Twinax cables in lengths of
1, 1.5, 2, 2.5, 3 and 5 meters, and active Twinax cables in lengths of 7 and 10 meters.
