The Moxa SFP-1G Series includes high-performance, industrial-grade SFP modules designed for fiber optic network expansion. Equipped with LC duplex or simplex WDM connectors, the modules support multimode and single-mode fibers with transmission distances up to 120 km. Fully IEEE 802.3z-compliant, the SFP-1G modules also support Digital Diagnostic Monitoring (DDM) and operate reliably across a wide temperature range (-40 to 85 °C for T-models).

Highlights:

• Supports multimode and single-mode fiber up to 120 km
• Models with DDM (digital diagnostics monitoring)
• WDM modules enable bidirectional transmission over one fiber
• Hot-pluggable LC connector
• Available types: SX, LX, LHX, ZX, EZX, WDM
• Industrial-grade temperature support (-40 to +85 °C)
• Compatible with many Moxa switches
