The Moxa SFP-1G Series includes a broad range of 1-port Gigabit Ethernet SFP modules designed as optional fiber connectivity accessories for Moxa Ethernet switches. These hot-pluggable modules support various fiber technologies—Multi-Mode, Single-Mode, and WDM—with transmission distances ranging from 300 meters up to 120 kilometers.

Fully IEEE 802.3z-compliant, they feature LC duplex or simplex connectors and support Digital Diagnostic Monitoring (DDM) for real-time performance feedback. With wide-temperature support (-40 to 85°C in T models) and compact design, these modules are well-suited for industrial-grade applications. All models are certified as Class 1 laser devices according to EN 60825-1.
