1G SFP multi-mode fiber transceiver for short-range Gigabit Ethernet links. Supports up to 550 m over MMF at 850 nm, fully compliant with SFP MSA and SFF-8472.
The DG-1G-SX-MM850 is a high-performance and cost-effective 1.25 Gbps SFP optical transceiver designed for short-range multi-mode fiber applications. Operating at 850 nm with a VCSEL laser and PIN photodiode, it supports transmission distances of up to 550 m over 50/125 µm MMF and 300 m over 62.5/125 µm MMF.
The module is fully compliant with the SFP Multi-Source Agreement (MSA) and SFF-8472, ensuring broad compatibility with switches, routers, servers, and network interface cards. It supports Digital Diagnostic Monitoring (DDM), allowing real-time monitoring of operating parameters such as temperature, voltage, bias current, and optical power.
Designed for reliability and easy integration, the DG-1G-SX-MM850 is ideal for enterprise networks, data centers, and campus environments requiring stable and efficient Gigabit fiber connectivity.
