Designed to support distances up to 300 metres, the DEM-431XT is a high performance 850nm Multi-Mode SFP+ transceiver. Supporting Full-duplex, 10 Gigabit speeds on Multi-Mode fibre cables. The DEM-431XT is 802.3ae 10GBASE-SR compliant and supports Full-duplex 802.3x Flow control. The DEM-431XT provides the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa.

  • Cost-effective solution for 10G fiber connection
  • Small form factor, allowing higher port densities for 10G connections
  • Lower power dissipation
  • Hot-pluggable
  • Compliant with Ethernet 802.3ae
  • Compliant with fiber MSA (Multiple Source Agreement)

D-Link’s 10G SFP+ Module series are hot-swappable SFP+ transceivers that plug into SFP+ slots on switches and support 10G Ethernet. The D-Link 10GBASE SFP+ Module Series transceivers offer customers a wide variety of 10G Ethernet connectivity options for data centers, enterprise wiring closets, and service provider transport applications.

Enhanced Small Form-factor Pluggable Format

The transceivers use the Enhanced Small Formfactor Pluggable format (SFP+). The SFP+ form factor is smaller than other form factors such as Xenpak, X2, and 10G XFP, ensuring lower costs, lower power disruption, and higher port density. They provide the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa, for the port to receive data from the network cable.

Hot Pluggable

All D-Link transceivers are hot-pluggable. You can connect a transceiver while the system is powered on without causing any problems. This permits modules to be added or removed without interrupting the network.
