HPE 835041-001 (MFA1A00-E007) InfiniBand EDR 100Gb/s QSFP28 Active Optical Cable, 7m: This is a 7-meter active optical cable (AOC) engineered for 100Gb/s InfiniBand EDR point-to-point interconnectivity. It is an HPE-branded version of the NVIDIA Mellanox MFA1A00-E007, with identical electrical and optical specifications. The cable uses VCSEL optics over multi-mode fiber within QSFP28 housings. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit.
Engineering Context
The 835041-001 is HPE's OEM-labeled equivalent of the Mellanox MFA1A00-E007. At 7 meters, passive copper is physically inviable for 100Gb/s EDR due to high insertion loss. This AOC provides the required reach for end-of-row and inter-rack connectivity. The cable is lighter, thinner, and provides complete EMI immunity compared to copper alternatives. Power consumption is under 2.5W per end.
Deployment & Use Cases
Linking HPE Apollo and ProLiant clusters across adjacent racks in InfiniBand EDR fabrics. High-speed RDMA storage-to-server connectivity. Financial trading platforms requiring deterministic latency over medium distances. Data center environments prioritizing airflow improvement with thinner cable profiles.
