The Moxa SFP-1G Series features reliable 1-port Gigabit Ethernet SFP modules designed as optional accessories for a broad range of Moxa industrial Ethernet switches. These hot-swappable modules support Digital Diagnostic Monitoring (DDM), differential LVPECL signals, and TTL signal detection. They are available for multi-mode, single-mode, and WDM fiber and support distances from 300 m to 120 km depending on the model.

With a wide operating temperature range (-40 to 85 °C for T-models) and a max power consumption of 1 W, these modules are ideal for demanding industrial network environments.
