DEM-431XT SFP+ 10GBASE-SR Multi-Mode Fibre Transceiver (550m)

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.

The transceivers all support 10G Ethernet, which results in very fast data transmissions of up to 10 Gbit/s. This is 10 times faster than Gigabit Ethernet and enables the switch to handle faster and higher data transmissions, making it very suitable for business needs.

The D-Link DEM-431XT, for instance, is a high-performance 10 Gigabit SFP+ (Enhanced Small Form-factor Pluggable) transceiver module designed for use with multimode fiber. Consequently, it’s an essential component for high-speed network connections in data centers, enterprise wiring closets, and service provider applications. The “SR” in its name stands for “Short Range,” indicating its use over shorter distances.

Therefore, here is a detailed description of the DEM-431XT:

Key Features and Specifications:

• Form Factor: SFP+ (Enhanced Small Form-factor Pluggable). The SFP+ form factor is a key advantage, in contrast to previous 10G transceivers (like XFP or X2), as it is smaller, thereby allowing for higher port density and lower power consumption on a switch.
• Speed: It supports 10 Gigabit Ethernet speeds (10 Gbit/s), which means it is ten times faster than standard Gigabit Ethernet. As a result, this makes it ideal for handling large data transmissions and high-bandwidth applications.
• Standard: Specifically, the DEM-431XT is compliant with the IEEE 802.3ae 10GBASE-SR standard.
• Fiber Media: It is designed for use with multimode fiber (MMF). Furthermore, the maximum distance it can cover depends on the specific type of multimode fiber used:
• Connector: It features a duplex LC connector for connecting two strands of fiber-optic cable.
• Digital Diagnostics Monitoring (DDM): In addition, the DEM-431XT often includes DDM functionality, which consequently allows for real-time monitoring of critical parameters such as transmitted and received power, temperature, and voltage. This helps in proactive network management and troubleshooting.
• Durability: It has a metal housing to reduce electromagnetic interference (EMI) and, as a result, increase its overall durability.
