Data General DG-25G-SR-MM850 is a 25G SFP28 multi-mode fiber transceiver for short-range 25 Gigabit Ethernet links. Supports up to 100 m over OM4 MMF at 850 nm, compliant with IEEE 802.3by 25GBASE-SR.
The DG-25G-SR-MM850 is a high-performance 25 Gbps SFP28 optical transceiver designed for short-range multi-mode fiber applications in high-density data center and enterprise environments. Operating at an 850 nm wavelengthusing a VCSEL laser transmitter and PIN photodiode receiver, it supports link distances of up to 100 m over OM4 MMF and 70 m over OM3 MMF.
The module is compliant with IEEE 802.3by 25GBASE-SR, SFP28 MSA, SFF-8431, and SFF-8472, ensuring broad interoperability with 25G-capable switches, routers, and network interface cards. It supports Digital Diagnostic Monitoring (DDM), enabling real-time monitoring of temperature, voltage, bias current, and optical transmit and receive power.
With its low power consumption, all-metal housing for superior EMI performance, and hot-pluggable SFP28 form factor, the DG-25G-SR-MM850 is an ideal solution for data centers, server interconnects, storage networks, and high-speed computing clusters requiring reliable and cost-effective 25G fiber connectivity.
