The module is designed for high-speed network connections and is compliant with RoHS standards. Its compact dimensions make it suitable for various networking applications.

## Long description

The D-Link DEM-431XT is a high-performance fiber optic SFP+ transceiver module designed to provide reliable 10G Ethernet connectivity. This hot-swappable module is engineered for demanding networking environments, offering data transfer rates of up to 10000 Mbit/s. It integrates seamlessly into compatible switches, ensuring efficient signal amplification and stable data transmission for enterprise-grade infrastructure.
Advantages
The primary benefit of the D-Link DEM-431XT is its compact SFP+ form factor, which allows for higher port density compared to older standards like XFP or Xenpak. Because the module is hot-pluggable, network administrators can install or replace units without powering down the switch, significantly reducing downtime. Furthermore, its low power consumption and robust design make it an energy-efficient choice for data centers and service provider networks that require consistent, high-speed performance.
Suitable for
Data center server interconnections
Enterprise network backbone upgrades
Service provider transport applications
High-density switch port expansion
This module may not be suitable for networks that do not support the SFP+ interface standard or for applications requiring long-range fiber connectivity beyond the specifications of this specific transceiver type. It is also not intended for use in non-optical networking environments.
Key specifications
Interface type: SFP+
Maximum data transfer rate: 10000 Mbit/s
Input voltage: 3.3 V
Maximum current: 0.3 A
Weight: 0.018 kg
Color: Stainless steel, Black
To use the D-Link DEM-431XT, simply insert the module into an available SFP+ slot on your network switch or router. The device is designed for plug-and-play operation, meaning the system will automatically detect the transceiver once it is securely seated. Ensure that the fiber optic cable is correctly aligned and connected to the module port to establish the link.
What to consider before purchase
Verify that your network switch or router has an available SFP+ port.
Ensure compatibility with your existing fiber optic cabling infrastructure.
Confirm that your network hardware supports the 10GBASE standard.
Usage recommendations: Always handle the transceiver with care to avoid damaging the optical interface. Keep the protective dust cap on the module until you are ready to connect the fiber cable to prevent contamination of the optical components.
