This 1000BASE-SX SFP transceiver is designed for high-performance gigabit data transmission over multimode fiber (MMF). Operating at a wavelength of 850 nm, it supports a maximum link distance of 550 meters via a duplex LC connector. The module is hot-pluggable, supports Digital Optical Monitoring (DOM), and complies with the SFP Multi-Source Agreement (MSA). It draws low power and is ideal for enterprise LANs, data center interconnects, and fiber switches requiring reliability and cost-efficiency. ? Key Features Supports 1 Gbps (1000BASE-SX) at 850 nm Maximum distance of 550 m over MMF Duplex LC interface for fiber connection Hot-pluggable SFP form factor Low power consumption (< 0.8 W typical) Digital Diagnostics Monitoring (DOM) (depending on variant) Compatible with many SFP-MSA devices
