The Omada ISM311LS is an industrial 1000BASE-LX SFP module for single-mode fiber, reaching 20 km and rated for -40°F to 185°F. It is the fiber uplink for camera poles, gatehouses and outdoor cabinets that see temperatures a standard SFP is not rated for.
Built for hard-to-reach fiber links
The module runs at 1310 nm over 9/125 µm single-mode fiber with an LC duplex connector. It is hot-swappable, supports DDM for checking the optical link, and follows SFP-MSA, so it fits Gigabit SFP slots on switches and routers.
Key features
- Up to 20 km on single-mode fiber at 1.25 Gbps
- Industrial temperature range: -40°F to 185°F (-40°C to 85°C)
- LC duplex, 1310 nm 1000BASE-LX optics
- Hot-swappable: install or replace with the switch running
- DDM support for monitoring the optical link
System requirements
A Gigabit SFP slot on a switch or router, and 9/125 µm single-mode fiber with LC connectors. Use a matching 1000BASE-LX module at the far end.

FAQs
How far can the ISM311LS run?
Up to 20 km over 9/125 µm single-mode fiber.
Does it work with multi-mode fiber?
No. It is a single-mode 1000BASE-LX module. Multi-mode runs need a multi-mode SFP.
What temperature range does it handle?
Operating temperature is -40°F to 185°F (-40°C to 85°C).
Can I swap it without powering down the switch?
Yes. The ISM311LS is hot-swappable.
Do I need the same module on both ends?
Use a matching 1000BASE-LX single-mode module at the far end.
