The Omada ISM321A-20 is an industrial 1000BASE-BX bi-directional SFP module that carries Gigabit traffic over a single strand of single-mode fiber, up to 20 km. It is rated for -40°F to 185°F, so it works in outdoor cabinets and unconditioned enclosures.
Built for hard-to-reach fiber links
It transmits at 1550 nm and receives at 1310 nm over 9/125 µm single-mode fiber with an LC simplex connector. Run it against a partner module with Tx 1310 nm and Rx 1550 nm at the far end. It is hot-swappable, supports DDM and follows SFP-MSA.
Key features
- One fiber strand up to 20 km at 1.25 Gbps
- Industrial temperature range: -40°F to 185°F (-40°C to 85°C)
- LC simplex, Tx 1550 nm / Rx 1310 nm 1000BASE-BX 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 one strand of 9/125 µm single-mode fiber with LC connectors. The far end needs a bi-directional module with Tx 1310 nm and Rx 1550 nm.
