The Moxa SFP-1G Series provides a versatile range of 1-port Gigabit Ethernet SFP modules, designed as optional accessories for Moxa’s industrial Ethernet switches. These hot-pluggable modules support a variety of fiber types—including Multi-Mode, Single-Mode, and WDM—and deliver extended transmission distances with advanced digital diagnostics (DDM) for real-time monitoring.

T models are built for extreme environments, operating from -40 to 85°C, and meet industrial-grade safety and EMC certifications. Compliant with IEEE 802.3z, all modules feature LC connectors (duplex or simplex) and meet Class 1 laser safety standards according to EN 60825-1.
