D-Link DEM-431XT-DD 10GBase-SR SFP Transceiver

The DEM-431XT is a robust 10 Gigabit SFP transceiver module built for short-range fiber links in enterprise and datacenter environments. It supports multi-mode fiber (MMF) operation at 850 nm and can reach distances of up to 300 meters on high-grade multimode cables. The module adheres to the IEEE 802.3ae (10GBASE-SR) standard and is compatible with MSA SFP slots, making it widely usable across switches and routers.Designed for flexibility and convenience, the DEM-431XT is hot-pluggable, meaning it can be installed or removed without shutting down your network equipment. It also supports Digital Diagnostics Monitoring (DDM), enabling real-time monitoring of parameters like transmit/receive power, temperature, and voltage. The compact form factor, lower power consumption, and solid performance make the DEM-431XT ideal for fiber uplinks, server interconnects, or short-distance aggregation links in data centers, campus networks, or enterprise setups.Technical SpecificationsSpecificationDetailModel / TypeDEM-431XTStandard ComplianceIEEE 802.3ae (10GBASE-SR)Fiber TypeMulti-mode fiber (MMF)Wavelength850 nmMaximum Distance300 meters (on OM3 / OM4)ConnectorDuplex LCHot-PluggableYesDigital DiagnosticsSupported (DDM)Power Supply3.3 VOperating Temperature0 °C to 70 °CStorage Temperature–40 °C to 85 °CHousingMetal enclosure (EMI shielded)
