D-Link DEM-431XT 10GBASE-SR SFP+ Multi-Mode Transceiver

A Clear Optical Path for High-Speed Connections The DEM-431XT adds a 10GBASE-SR connection to a compatible SFP+ host port. It is designed for multimode fibre links in business, aggregation and data-centre networks. A duplex LC connection and 10 Gbps interface keep the required host and cable choice clear. The specified link reach is OM3 up to 300 m. Match the fibre grade, connectors, optical standard and remote module before installation. A physically fitting module alone does not establish host compatibility or an operational link. Highlights Connection Standard 10GBASE-SR at 10 Gbps. SFP+ module with duplex LC connector. OM3 up to 300 m. Link Requirements Multimode fibre; duplex LC connection. 850 nm. Compatible host port and supported module revision required. Installation Hot-pluggable design in a supported host. Match both ends and test the completed link. 5-year warranty. Key Features Choose the Correct Host Interface This module uses the SFP+ form factor and the 10GBASE-SR connection standard. Check the host’s exact compatibility list, supported speed and hardware revision. Similar-looking SFP, SFP+, QSFP+ and QSFP28 modules are not automatically interchangeable. Match the Cable to the Link The duplex LC interface requires multimode cabling. Use the appropriate duplex fibre patching at both ends. Single-mode and multimode optics use different fibre systems; an identical connector does not make them equivalent. Plan the Required Distance The published reach is OM3 up to 300 m. The stated maximum depends on the specified fibre grade and acceptable link loss. Patch panels, connectors and cable condition affect the optical path, so validate the total link rather than relying on distance alone. Make Maintenance More Practical Hot-pluggable construction allows a supported host to accept or release the module without powering down the chassis. Removing the module still interrupts the link that uses it. Schedule the work and provide a tested alternate path where that connection is carrying production traffic. Check the Complete Pair The remote connection must support 10GBASE-SR at the intended speed. Match the optical standard and fibre system at both ends, keep connectors clean and protect unused ports with their caps. Do not connect incompatible wavelengths or fibre types simply because the module fits. Install Within the Host Limits The module operating range is 0°C to 70°C. Ensure the host provides the specified power, ventilation and supported firmware. Choose industrial-rated optics separately when an installation needs temperatures outside this commercial operating range. Summary The DEM-431XT provides a focused 10GBASE-SR connection for a compatible SFP+ host. Specify the correct fibre, connectors and remote optic with the module to build a link that suits the installation. Frequently Asked Questions Will It Work in Any Similar-Looking Slot?ExpandCollapse No. The host must explicitly support this SFP+ module, connection standard, speed and hardware revision. Check the switch or adapter compatibility list before ordering. Which Cable Does It Need?ExpandCollapse Use multimode fibre with duplex LC connections. The cable and remote interface must match the connection standard. What Is the Maximum Link Distance?ExpandCollapse OM3 up to 300 m. This assumes the specified cable or fibre grade and a link within the permitted loss and installation requirements. Can It Be Fitted Without Turning Off the Switch?ExpandCollapse The module is hot-pluggable in a supported host. Fitting or removing it can still interrupt that link, so plan maintenance around the traffic it carries. Can It Replace a Different Optical Standard?ExpandCollapse Do not assume so. This is a 10GBASE-SR optic. Match the remote standard, fibre type and connectors; another module with the same shape may use a different optical system. Are Connection Cables Included?ExpandCollapse No cable is included in this transceiver offer. Select the required cable or fibre patching separately. Protect and clean fibre connectors before commissioning the link. 더 보기
