HPE QSFP28 To SFP28 Adapter 845970-B21 849444-001

The HPE QSFP28 to SFP28 Adapter is a simple, practical connectivity accessory that allows you to adapt QSFP28-based hardware to work with SFP28 interfaces where required. It’s designed for data centre environments where you need flexibility in how you interconnect network equipment, especially during upgrades or when standardising across mixed interface types.

This adapter excels in situations where you’re transitioning between 25Gb and 100Gb ecosystems, managing mixed inventories, or extending the life of existing cabling and optics while modernising switching or server connectivity. It’s particularly useful when you want a neat, supported way to bridge interface formats without redesigning the whole link approach.
