The Moxa SFP-1G Series delivers versatile 1-port Gigabit Ethernet SFP modules that serve as accessories for a wide range of Moxa industrial Ethernet switches. These hot-pluggable modules support Digital Diagnostic Monitoring (DDM) and comply with IEEE 802.3z. They use differential LVPECL signaling and TTL detection to provide reliable data transmission across distances ranging from 300 m to 120 km depending on the model.

Available in multi-mode, single-mode, and WDM variants, the series is well-suited for rugged environments with models operating at temperatures from -40 to 85 °C.
