D-link Systems DEM-431XT 10gbase-sr Sfp+ Transceiver

Product Description

The D-Link Systems DEM-431XT is a 10GBase-SR multimode SFP+ optical transceiver designed for high-speed fiber network deployments. The module plugs into an SFP+ port on a compatible switch or network interface card and transmits data over multimode fiber at 10 Gigabit Ethernet speeds. This form factor is a standard in enterprise and data center environments where short-reach, high-bandwidth fiber connections are required. Installation is typically handled by a network technician or low-voltage cabling professional working within structured cabling or data center infrastructure.

The DEM-431XT is suited for short-reach 10GbE links in enterprise networks, data centers, and server rooms. The 10GBase-SR designation indicates operation over multimode fiber, making it appropriate for intra-building backbone runs and top-of-rack switch interconnects where distances are measured in meters rather than kilometers. It is sold as a single unit and fits applications where hot-swappable optical modules are required for uplink or inter-switch connections.

Key Features

• 10GBase-SR standard for short-reach multimode fiber operation
• SFP+ form factor supports hot-swap installation without powering down the host device
• Designed for multimode fiber infrastructure commonly found in enterprise and data center cabling plants
• Single-unit packaging suitable for individual port upgrades or sparing

Compatibility

Designed as an OEM-style replacement or expansion module for network switches and network interface cards equipped with SFP+ ports supporting 10GBase-SR multimode fiber operation.

Installation Notes

Installation should be performed by a qualified network technician familiar with fiber optic handling procedures. Always clean fiber endfaces before insertion and avoid exposing the optical port to contaminants or direct viewing of the laser aperture. The SFP+ module is hot-swappable in most host devices, but confirm host platform documentation before insertion under live conditions. Handle with an ESD wrist strap to prevent electrostatic damage to the module circuitry.
