The Omada ISM311LM is an industrial 1000BASE-SX SFP module for multi-mode fiber, rated for -40°F to 185°F. It suits outdoor cabinets, pole enclosures and unconditioned equipment rooms where a standard SFP would be out of its temperature range.
Built for hard-to-reach fiber links
The module runs at 850 nm over 50/125 µm or 62.5/125 µm multi-mode fiber with an LC/UPC connector, to a maximum cable length of 550 m. It is hot-swappable, supports DDM and follows SFP-MSA, so it drops into live Gigabit switches.
Key features
- Up to 550 m on multi-mode fiber at 1.25 Gbps
- Industrial temperature range: -40°F to 185°F (-40°C to 85°C)
- LC/UPC, 850 nm 1000BASE-SX 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 50/125 µm or 62.5/125 µm multi-mode fiber with LC connectors. Use a matching 1000BASE-SX module at the far end.

FAQs
How far can the ISM311LM run?
Up to 550 m, per TP-Link's maximum cable length, on multi-mode fiber.
Does it work with single-mode fiber?
No. It is a multi-mode 1000BASE-SX module. Single-mode runs need a single-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 ISM311LM is hot-swappable.
Do I need the same module on both ends?
Use a matching 1000BASE-SX multi-mode module at the far end.
