The Moxa SFP-1G Series consists of high-performance 1-port Gigabit Ethernet SFP modules designed for industrial applications. Fully IEEE 802.3z compliant, these hot-swappable modules support Digital Diagnostic Monitoring (DDM), feature differential LVPECL signaling and TTL signal detection, and are certified as Class 1 laser products. With support for multi-mode, single-mode, and WDM fiber types, the modules cover distances from 300 m to 120 km.

Wide-temperature models operate from -40 to 85 °C, making them ideal for deployment in harsh industrial environments.
