QK724A HPE Transceiver

High-Density Fibre Channel Optical Connectivity featuring short-reach MMF links with the QK724A

The QK724A is an HPE 16G Fibre Channel SFP+ SR transceiver engineered for predictable SAN throughput and low-latency fabric operations across short-reach multimode runs. Designed for 16G FC switch/director edge ports and HBA uplinks, the QK724A enables consistent link behavior where deterministic storage traffic and clean optics interoperability are required.

Optimized for multimode fibre at 850nm, the QK724A supports intra-row and adjacent-rack connectivity up to 400m, aligning with modern data centre topologies that keep FC fabrics compact and resilient. The LC duplex interface simplifies patching density in high-port-count environments, while the SFP+ form factor preserves PCIe slot budget by avoiding add-in conversion hardware. For storage architects, deploying the QK724A helps standardize optical modules across array front-end ports and fabric inter-switch links, reducing operational variance and supporting scalable FC zoning and trunking strategies.

Why Choose the QK724A?

The QK724A provides an efficient density-to-performance profile for 16G FC fabrics by delivering short-reach optical connectivity without introducing platform complexity. Standardizing on the QK724A supports reliable link bring-up, repeatable cabling practices, and controlled expansion as ports scale across directors, top-of-rack FC switches, and host connectivity.

HPE designs optics with an enterprise engineering focus on compatibility, sustained operation, and predictable behavior under continuous SAN load. The result is a transceiver approach aligned to data centre standards for structured cabling, serviceability, and lifecycle planning across FC storage networking environments.

Key Applications:

• 16G Fibre Channel SAN switch and director uplinks
• HBA connectivity for storage host access
• FC fabric edge ports in high-density rows
