SFP-10G-SR-X Description

The SFP-10G-SR-X is a Cisco extended-temperature multirate 10GBASE-SR SFP+ transceiver for short 10G links over multimode fiber at sites that exceed commercial temperature limits. The module reaches 300 m on OM3 and 400 m on OM4 or OM5 at 850 nm, operates from -5 to 85°C and draws up to 1W. The module carries 10GBASE-SR, 10GBASE-SW and OTU2e signals over multimode fiber only.

SFP-10G-SR-X is the extended-temperature multirate version of the 850 nm SR optic: it adds 10GBASE-SW and OTU2e support and a -5 to 85 degrees C rating, while SFP-10G-SR supports 10GBASE-SR only at the commercial range, with the same 300 m on OM3 and 400 m on OM4 or OM5. Ethernet-only links in commercial-temperature locations can use SFP-10G-SR. SFP-10G-SR-S is the S-Class listing and carries Cisco’s no-FCoE note, so FCoE links need SFP-10G-SR-X or SFP-10G-SR. Sites that need an industrial temperature class or CPRI options move to SFP-10G-SR-I.

Ordering Checklist

  • Host support: Confirm the target platform and port are listed for this optic in Cisco’s Transceiver Module Group Compatibility Matrix (tmgmatrix.cisco.com). A host can reject an optic that fits the cage but is not on its supported list.
  • Fiber type and length: Use multimode fiber at 850 nm: up to 300 m on OM3, up to 400 m on OM4 or OM5. OM3 links fall 100 m short of OM4 or OM5, so confirm the cable grade before ordering.

    Our approved vendor list is short, and Layer23 has earned a permanent spot.

    Vendor management often gets complicated. Layer23 keeps it simple. Minor delay in delivery, but everything was in order.

Questions & Answers

  • How far does SFP-10G-SR-X reach on OM1, OM2 and FDDI-grade multimode fiber?

    SFP-10G-SR-X reaches 33 m on OM1 fiber and 82 m on OM2 fiber. On FDDI-grade 62.5 micron fiber the reach is only 26 m. Older fiber grades fall far short of the OM3 and OM4 distances, so check the installed grade before planning a link.
  • What transmit and receive power ranges does SFP-10G-SR-X specify?

    SFP-10G-SR-X transmits at -1.2 to -7.3 dBm and receives at -1.0 to -9.9 dBm. The receive range sets the optical loss budget that patch cords and connectors must stay inside on the multimode link.
  • Which wavelength window and minimum link length apply to SFP-10G-SR-X?

    SFP-10G-SR-X works inside an 840 to 860 nm transmit and receive window, and the cabling between ends must be at least 2 m. Patch runs below the 2 m minimum are outside the specified operating distance.
  • Can SFP-10G-SR-X be used on single-mode fiber?

    No. SFP-10G-SR-X is a multimode optic at 850 nm and carries 10GBASE-SR, 10GBASE-SW and OTU2e signals over multimode fiber only. Reach is 300 m on OM3 and 400 m on OM4 or OM5, so a single-mode plant needs a different 10G optic.
