HPE 835040-001 (MFA1A00-E005) InfiniBand EDR 100Gb/s QSFP28 Active Optical Cable, 5m: This is a 5-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-E005, with identical electrical and optical specifications. The cable integrates VCSEL optics and 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 835040-001 is HPE's OEM-labeled equivalent of the Mellanox MFA1A00-E005. At 5 meters, passive copper cables become heavy and difficult to route. This AOC provides a lightweight, flexible alternative with a tighter bend radius and complete EMI immunity. It maintains deterministic latency required for RDMA operations. Power consumption is under 2.5W per end.
Deployment & Use Cases
HPE Apollo and ProLiant Gen10 servers connecting to InfiniBand EDR fabric switches. Low-latency HPC clusters and supercomputing nodes. RDMA-based storage clusters using InfiniBand. Inter-rack connectivity where copper reach is marginal at 100Gb/s.

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with HPE Apollo Systems, HPE ProLiant servers (DL380, XL170r) with ConnectX-4/ConnectX-5 VPI adapters, and Mellanox Switch-IB 2 series switches (SB7800/SB7890). Not compatible with standard 100GbE Ethernet switches unless the port supports VPI mode. Not backward compatible with legacy QDR (40G) ports without auto-negotiation confirmation. This is a direct QSFP28-to-QSFP28 cable; does not support breakout. Fixed 5m length.
