Sfp+ Lrm Module 10 Gigabit Ethernet Sfp+

The Extreme Networks SFP+ LRM transceiver is a 10 Gigabit Ethernet module with a 1310 nm wavelength, multimode fiber support, an LC connector, and a listed 220 m link reach, suited to network administrators connecting compatible equipment over fiber.

Recommended For

• Network administrators connecting 10GbE switches over existing multimode fiber runs up to 220 m, when the ports are confirmed to support LRM.
• IT teams reusing legacy OM1 or OM2 multimode fiber for a 10GbE link, provided they use the mode-conditioning patch cord Extreme specifies.
• Teams building short 10GbE fiber links between network closets or nearby equipment rooms, where LC fiber connections and the module’s supported reach fit the installation.
• Network teams with a short standard single-mode fiber run of up to 300 m that specifically needs an LRM optic and has verified port compatibility.

Real-World Use Scenarios

• When upgrading two switches connected by existing multimode fiber, use a matched pair of LRM modules to create a 10Gb link without replacing the fiber, provided the run is within its supported reach and the switch models support the modules.
• For a 10Gb uplink between wiring closets over older OM1 or OM2 multimode fiber, LRM can make the existing cabling usable; Extreme specifies a mode-conditioning patch cord for these fiber types, and actual reach depends on the installation.
• When connecting switches over OM3 multimode fiber, LRM provides a 10Gb optical link without a mode-conditioning patch cord; check the fiber run and device compatibility before deployment.
• For a short link over standard single-mode fiber, LRM may be an option when the endpoints and fiber are suitable; Extreme lists a nominal reach of up to 300 meters, so it is not a substitute for longer-reach optics.
