The Moxa SFP-1G Series consists of high-performance 1-port Gigabit Ethernet SFP modules designed as optional accessories for a wide range of industrial Moxa Ethernet switches. Supporting various fiber types—Multi-Mode, Single-Mode, and WDM—the modules deliver transmission distances ranging from 300 meters to 120 kilometers.

These hot-pluggable modules offer IEEE 802.3z compliance, Digital Diagnostic Monitoring (DDM), LVPECL differential I/O, TTL signal detection, and either LC duplex or LC simplex (WDM only) connectors. T models support a wide operating temperature range of -40 to 85°C, making them ideal for harsh environments. All modules are certified as Class 1 laser products under EN 60825-1.
