Dell 10Gb Ethernet Module SFP+ SR Optical Transceiver

The Dell HN12K is a 10 Gigabit Ethernet SFP+ SR optical transceiver that brings reliable high-speed connectivity to Dell PowerEdge servers and compatible network gear. It delivers 10,000 Mbit/s throughput, giving administrators a quick way to move large data sets, support virtualization clusters, or push storage traffic without adding complex infrastructure.

Designed for seamless integration, the module plugs into an open SFP+ slot and links through an LC duplex connector over 10GBase-SR multimode fiber. Distances up to 300 meters are possible, making it a practical choice for connecting racks on the same floor, joining separate rooms in a data center, or bridging nearby buildings on a campus network.

Installation is straightforward. The hot-pluggable design lets you insert or replace the unit while servers stay powered, so maintenance windows remain short and critical workloads stay online. Administrators also gain access to built-in diagnostic monitoring that reports optical power levels, temperature, and other key metrics through standard management tools.

A housing made from stainless steel withstands repeated insertions in dense rack environments and helps protect the optics in demanding conditions. Whether you need to boost backbone bandwidth, expand a hyper-converged cluster, or improve storage area network performance, the Dell HN12K provides a dependable, cost-effective path to 10 Gigabit speeds.
