The NVIDIA Mellanox MFS1S00-H003V is an active optical cable (AOC) that links two QSFP56 ports at up to 200 Gb/s over a fixed 3m multimode fiber assembly. Manufacturer Part Number: MFS1S00-H003V. It IS a factory-terminated, integrated optical-transceiver cable for InfiniBand HDR and 200GbE Ethernet. It is NOT a Direct Attach Copper (DAC) cable, NOT a passive fiber patch cord, and NOT a separate transceiver module. Condition: Refurbished, fully tested.
Engineering Context. The cable carries 4 lanes of 50 Gb/s PAM4 modulation over multimode fiber, aggregating to 200 Gb/s. Integrated VCSEL-based optics are factory-aligned and tested, eliminating the dirty-end-face and connector-loss issues that arise with separate transceivers plus MPO patch cords. Power dissipation stays within the QSFP56 envelope, and the LSZH (Low Smoke Zero Halogen) jacket meets data-center fire-safety requirements. The QSFP56 connectors are mechanically backward compatible with QSFP28 cages, allowing 100 Gb/s operation on legacy 100G hosts.
Deployment & Use Cases. The MFS1S00-H003V is intended for high-performance compute clusters, AI/ML training fabrics, GPU-dense server interconnects, and InfiniBand HDR storage networks. Typical deployments include rack-to-rack and row-to-row links inside data centers, connecting NVIDIA Quantum HDR switches (MQM87xx family) to ConnectX-6 HCAs/NICs in compute and storage nodes. Common workloads: distributed deep-learning training, large-language-model inference clusters, HPC simulation, financial low-latency fabrics, and 200GbE Ethernet uplinks where AOC reach exceeds the limits of DAC.
Technical Specifications.
Manufacturer Part Number: MFS1S00-H003V
Brand: NVIDIA Mellanox
Form Factor: QSFP56 to QSFP56
Cable Type: Active Optical Cable (AOC), fixed length, integrated optics
Data Rate: 200 Gb/s (4 lanes × 50 Gb/s PAM4)
Protocols: InfiniBand HDR and 200GbE Ethernet (VPI-capable on supported hosts)
Length: 3m
Jacket: LSZH (Low Smoke Zero Halogen)
Backward Compatibility: 100 Gb/s on QSFP28 hosts
Condition: Refurbished
Compatibility & Constraints. Compatible with NVIDIA Quantum HDR switches (MQM87xx family) and ConnectX-6 HCAs/NICs that expose QSFP56 ports. Operates at 100 Gb/s when paired with QSFP28 ports at one or both ends. The cable is NOT compatible with QSFP-DD 400 Gb/s ports without a passive QSFP56-to-QSFP-DD adapter. It is a fixed-length, factory-terminated assembly — fiber and connectors cannot be detached or re-terminated. For Ethernet-only deployments, confirm that the host adapter and driver support 200GbE on the relevant port.
