D-Link DEM-431XT 10GBASE-SR SFP+ Transceiver
The D-Link DEM-431XT is a high-performance 10 Gigabit SFP+ optical transceiver designed for short-range, high-speed fiber networking. Supporting the 10GBASE-SR standard, it provides reliable 10GbE connectivity over multimode fiber (MMF) for distances up to 300 meters, making it ideal for data centers, enterprise networks, server rooms, and campus environments.
Operating at an 850 nm wavelength and powered by a 3.3V supply, the DEM-431XT delivers stable and efficient optical transmission while maintaining compatibility with standard SFP+ interfaces. Its hot-swappable design enables easy installation and replacement without interrupting network operations. This model is supplied without Digital Diagnostic Monitoring (DDM) functionality.
