NVIDIA Mellanox MFS1S00-H003E 200Gb/s HDR InfiniBand QSFP56 Active Optical Cable, 3m LSZH: This is a 3-meter active optical cable (AOC) engineered for QSFP56-to-QSFP56 200Gb/s HDR InfiniBand interconnects. The cable uses VCSEL optics over multi-mode fiber inside a Low Smoke Zero Halogen jacket. This is a fixed-length integrated cable assembly, not a transceiver paired with a separate fiber patch cord. This is a refurbished unit.
Engineering Context
The MFS1S00-H003E carries 200Gb/s using 4 lanes at 50Gb/s PAM4 modulation, conforming to the InfiniBand HDR electrical and protocol specification. At 3 meters it targets intra-rack and rack-adjacent links where 200G passive copper assemblies become bulky and hard to route. Compared to 200G DAC, the AOC is significantly lighter, has a tighter bend radius (typically 30mm minimum), and provides full EMI immunity over the optical span. Factory-terminated optical end-faces eliminate the field contamination issues common to MPO patch cords. The LSZH jacket meets data-center fire-safety codes that prohibit halogenated PVC.
Deployment & Use Cases
Top-of-Rack HDR fabric links connecting NVIDIA Quantum QM8700 or QM8790 switches to ConnectX-6 HCAs in HPC and AI compute nodes. GPU-to-GPU and GPU-to-storage interconnects in DGX-class clusters running NCCL collectives. NVMe-over-Fabrics (NVMe-oF) initiator-to-target links that require HDR bandwidth without the weight and bend-radius constraints of 200G copper.

Compatibility & Constraints
Compatible with NVIDIA Quantum HDR switches (QM8700, QM8790) and ConnectX-6 VPI/HDR adapters operating in 200Gb/s InfiniBand mode. Compatible with HDR100 (100Gb/s, 2x50G PAM4) when negotiated. Not compatible with EDR (100Gb/s NRZ on QSFP28) or FDR (56Gb/s) host ports that do not support PAM4 signaling at the QSFP56 electrical interface. This is a direct QSFP56-to-QSFP56 assembly; it does not break out into 4x SFP56 or 2x HDR100 segments. Length is fixed at 3m and cannot be extended.
