D-Link DEM-431XT 10GBase-SR SFP+ Multi-Mode Transceiver 300m
The D-Link DEM-431XT is a high-performance 850nm multi-mode SFP+ transceiver designed to deliver reliable 10 Gigabit Ethernet connectivity for data centres, enterprise wiring closets, and service provider networks. This hot-swappable module supports 10G Ethernet speeds over multi-mode fibre for distances of up to 300 metres, making it ideal for high-speed network infrastructure upgrades across Australian businesses.
Why Choose the DEM-431XT?
-
10 Gigabit Ethernet Performance: Delivers data transmission speeds up to 10 Gbit/s, 10 times faster than Gigabit Ethernet, for demanding business applications
-
Hot-Pluggable Design: Easily add or remove the transceiver while your system is powered on without disrupting network operations
-
Compact SFP+ Form Factor: Smaller than Xenpak, X2, and 10G XFP modules for lower costs, reduced power consumption, and higher port density
-
Multi-Source Agreement (MSA) Compliant: Ensures compatibility across multiple vendors' networking equipment
-
Low Power Consumption: Maximum 1W power draw ensures efficient operation and reduced heat generation
-
IEEE 802.3ae Compliant: Fully compliant with 10GBASE-SR standards for guaranteed interoperability
High-Speed 10G Ethernet Connectivity
The DEM-431XT transceiver supports 10 Gigabit Ethernet transmission speeds, enabling your network switches to handle significantly faster data transfers. This makes it perfect for enterprises requiring high-bandwidth applications such as video streaming, large file transfers, virtualisation, cloud computing, and business-critical data backups. The module operates at an 850nm wavelength and uses a Duplex LC connector for secure, reliable multi-mode fibre connections.
Enhanced Small Form Factor (SFP+)
Built to the Enhanced Small Form-factor Pluggable (SFP+) standard, the DEM-431XT delivers superior port density compared to older transceiver formats. The compact design reduces overall system costs, lowers power consumption, and provides the necessary signal amplification for seamless data transmission between network cables and switch ports.
Flexible Deployment for Data Centres and Enterprises
The DEM-431XT is engineered for versatile deployment across data centres, enterprise wiring closets, and service provider transport applications. Whether you're upgrading an existing network or building a new 10G infrastructure, this transceiver offers the performance, reliability, and compatibility Australian businesses demand. The hot-pluggable design allows for easy maintenance and network expansion without downtime.
