10GBase-LR SFP+ Transceiver

The Cisco SFP-10G-LR= is a hot-swappable SFP+ transceiver delivering 10 Gbps over single-mode fiber at 1310 nm. It connects through an LC duplex interface and reaches up to 10 km on standard G.652 fiber. The module fits Cisco Nexus 5000 and 7000 series switches for data-center, wiring-closet or service-provider links.

Replaces shorter-reach optics

Swapping a 10GBase-SR or LRM module for this LR version extends the link from hundreds of metres to 10 km without changing switch line cards. The jump is worth it when campus buildings, metro rings or campus-to-data-center runs exceed the reach of multimode or LRM optics and single-mode cable plant is already in place.

Steady 10 Gbps over 10 km

The transceiver maintains the full 10 Gbit/s line rate across the entire 10 km distance on G.652 single-mode fiber. Single-mode transmission keeps attenuation and dispersion low, so the optical budget stays closed during continuous operation. Hot-swappable insertion lets you add or replace links without powering down the chassis.

Questions about this item

Will the 0.5 inch width and 2.2 inch depth fit a standard SFP+ cage in a Cisco Nexus 5000 Series Switch?

Yes, the module follows the SFP+ form factor at 0.3 inch high, 0.5 inch wide and 2.2 inch deep, matching the cage dimensions used in Nexus 5000 and 7000 Series switches.

Is the transceiver hot-swappable, and what is the common mistake when inserting it?

It is hot-swappable; the frequent error is not pushing the module until the latch clicks, leaving the LC duplex connector slightly unseated and causing link flaps.

What single-mode fiber specification and connector polish should be used for a 10 km link at 1310 nm?

Use OS2 single-mode fiber compliant with G.652 and LC connectors with UPC polish to achieve the rated 10 km reach at 1310 nm.
