HPE 849444-001 QSFP28 to SFP28 25GbE Network Adapter
Overview
The HPE 849444-001 is a high-speed network adapter designed for modern data center and enterprise networking environments. Its primary function is to provide connectivity flexibility by converting a 100GbE QSFP28 port into a 25GbE SFP28 port. This module addresses the common challenge of integrating lower-speed 25GbE devices into a high-density 100GbE switching fabric without requiring a complete hardware overhaul or leaving expensive ports unused. This adapter allows network architects to maximize the utility of their existing high-speed switching infrastructure. By enabling a QSFP28 port to accept a standard SFP28 transceiver, it facilitates a cost-effective migration path and supports mixed-speed environments. The conversion is purely physical, requiring no complex configuration or software, which ensures seamless and reliable performance for connecting servers or other switches at 25GbE speeds. Deployment is a straightforward, tool-less process. As a hot-pluggable module, the adapter can be installed or removed from a compatible HPE network switch without causing service interruptions. Its passive, compact design requires no external power and fits neatly within the QSFP28 port cage. This simplicity makes it an essential component for teams needing to adapt their network topology on demand while maintaining operational uptime.
