📝 Key Features & Applications

Purpose-built for BladeSystem: Designed specifically for HPE BladeSystem c-Class environments to bridge a QSFP+ port to an SFP+ device.

Mixed-Speed Connectivity: Enables a 40GbE QSFP+ port to connect with 10GbE SFP+ devices, simplifying topology and expanding compatibility.

Legacy Integration: Allows a 10GbE SFP+ transceiver or Direct Attach Cable (DAC) to be used in a 40GbE QSFP+ uplink on supported HPE BladeSystem c-Class interconnects.

Cost-Effective: Helps reduce costs and avoid port underutilization by enabling the use of existing SFP+ optics and cabling.

Passive Design: Requires no external power, making it a simple plug-and-play solution.

Cable Management: Compact, low-profile design helps reduce cable clutter in blade chassis and rack enclosures.

Deployment Scenarios: Ideal for mixed-speed environments, supporting phased migrations from 10GbE (SFP+) to 40GbE (QSFP+) topologies.

🏢 Applications

Data center blade server environments

Interconnecting 40GbE-capable infrastructure with SFP+ based 10GbE links
