The Moxa SFP-1G Series provides high-performance 1-port Gigabit Ethernet SFP modules designed for use with a wide range of Moxa industrial Ethernet switches. These hot-pluggable transceivers support Digital Diagnostic Monitoring (DDM), differential LVPECL inputs and outputs, and TTL signal detection. With models supporting multi-mode, single-mode, and WDM fiber, the series enables transmission distances of up to 120 km—ideal for building scalable and robust networks.

The wide-temperature models (-T) operate from -40 to 85 °C, making them suitable for extreme industrial environments. The series complies with IEEE 802.3z and Class 1 laser product regulations per EN 60825-1.
