D-Link DEM-431XT-DD Compatible 10GBASE-SR SFP+ Transceiver Module (MMF, 850nm, 300m, LC, DOM)
This D-Link DEM-431XT-DD compatible SFP+ transceiver carries 10GBASE-SR and 10GBASE-SW traffic over multimode fiber at 850nm through an LC duplex interface, reaching 300 meters on OM3, 400 meters on OM4, and 82 meters on older OM2. Short-reach optics cover the distances that actually occur inside a building, at a fraction of what a long-reach module costs, which makes them the default choice for switch-to-switch links within a rack row or between floors.
The DD suffix in D-Link's part number marks digital diagnostics, and this module carries them: temperature, voltage, and optical power are reported in real time, so a dirty connector or fading transmitter shows up in monitoring before the link drops. It meets the SFP+ MSA, SFF-8431, SFF-8432, and IEEE 802.3ae standards for clean interoperation in mixed-vendor networks.
Every unit is programmed with D-Link EEPROM coding and tested in D-Link 10G switches, routers, and network interface cards before it ships, so the port recognizes it exactly as it would the OEM DEM-431XT-DD, at a much lower price.
