The Omada SM311LM is a 1000BASE-SX Gigabit SFP module for multi-mode fiber, reaching 550 m on 50/125 µm fiber and 275 m on 62.5/125 µm. It covers the in-building and short campus runs where you already have multi-mode fiber in place.
Built for multi-mode uplinks
The module runs at 850 nm with an LC duplex connector and is hot-swappable, so it can go into a live switch. Digital Diagnostic Monitoring reports link health back to the host. It follows the SFP Multi-Source Agreement and is rated from 32°F to 158°F.
Key features
- Up to 550 m on 50/125 µm multi-mode fiber, 275 m on 62.5/125 µm
- LC duplex, 850 nm 1000BASE-SX optics
- Hot-swappable: install or replace with the host running
- DDM support for monitoring the optical link
System requirements
A Gigabit SFP slot on a switch or router, and 50/125 µm or 62.5/125 µm multi-mode fiber with LC connectors. Use a matching 1000BASE-SX multi-mode module at the other end of the link.
