D-Link DEM-431XT SR transceiver module 10 Gigabit SFP +

The D-Link DEM-431XT is a high-performance 10 Gigabit Small Form-factor Pluggable Plus (SFP+) transceiver module designed for use with D-Link switches and other compatible networking equipment. It supports 10GBASE-SR standard, enabling short-range optical communication over multimode fiber (MMF) at distances up to 300 meters with OM3 fiber. The module is hot-pluggable, allowing for easy installation and replacement without powering down the system.

This transceiver operates at a nominal wavelength of 850 nm and features a duplex LC connector interface. It is compliant with the SFF-8431 and SFF-8432 MSA standards, ensuring interoperability with a wide range of SFP+ ports. The DEM-431XT is ideal for high-speed data center interconnects, enterprise network backbones, and storage area networks (SANs) requiring reliable 10 Gigabit connectivity over short distances.
