HP QSFP+ to SFP+ Adapter

This HP adapter connects a QSFP+ port to an SFP+ transceiver. It allows direct interconnection between equipment using different form factors in data-centre and enterprise environments.

Suitable for technicians linking QSFP+ and SFP+ gear

Not suited for networks that require native QSFP+ to QSFP+ or SFP+ to SFP+ links without conversion. Buyers needing passive copper twinax or active optical cables should select the appropriate cable assembly instead.

Connector configuration: QSFP+ to SFP+

The device presents one QSFP+ connector on the first end and one SFP+ connector on the second end. This fixed gender-change layout determines whether the adapter matches the port and module combination in your rack.

Questions about this item

Will the QSFP+ connector or SFP+ module need periodic replacement?

The adapter is a passive mechanical converter with no active electronics, so neither the QSFP+ nor the SFP+ interface requires scheduled replacement.

What is the first limit reached under sustained use?

As a passive gender changer it has no throughput ceiling, thermal throttle point or duty-cycle rating of its own.

How much heat or noise does the adapter generate when running continuously?

It produces no heat and no noise because it contains no powered components.
