Identity & Definition
This enterprise active optical cable, the NVIDIA Mellanox MFS1S00-H020V, is a 20-meter Active Optical Cable (AOC) with QSFP56 connectors supporting 200Gb/s over both InfiniBand HDR and 200GbE Ethernet via VPI (Virtual Protocol Interconnect). This is an active optical cable, not a passive DAC — it contains optical transceivers at each end for electrical-to-optical conversion. This is a fixed-length assembly, not a pluggable transceiver with detachable patch cord. Condition: NEW.
Engineering Context
At 20 meters, this AOC addresses inter-row and cross-zone connectivity in large-scale data centers where passive copper DACs cannot reach (DAC max ~3m at 200G). The active optical design provides complete EMI immunity, deterministic latency, and stable 200Gb/s PAM4 transmission when routed through ceiling plenums or underfloor trays alongside high-voltage power cables. VPI support means the same physical cable operates in either InfiniBand HDR or 200GbE mode depending on port configuration — protocol is not auto-negotiated and must be explicitly set on the host adapter. Minimum bend radius is 35mm.
Deployment & Use Cases
Inter-row connectivity linking End-of-Row switches to Core/Spine switches in distant racks within Quantum HDR InfiniBand fabrics. HPC cluster expansion connecting separate compute node islands into a unified HDR fabric. Cross-zone high-bandwidth links to NVMe-oF storage arrays in separate physical zones. Any 200Gb/s connection requiring more than 3 meters of reach in VMware ESXi, KVM, or bare-metal environments.

Compatibility & Hard Constraints
VPI Cable: Supports both InfiniBand HDR and 200GbE Ethernet. Protocol must be explicitly configured on host port — not auto-negotiated. Not Compatible with 100G NRZ Ports: Requires ports supporting native 200Gb/s PAM4 modulation. Legacy 100G QSFP28 NRZ-only ports will not link. Active Optical: Consumes power at each end. Host platform must provide adequate thermal dissipation for active QSFP56 modules. Fixed Length: 20 meters cannot be shortened. For shorter distances, consider DAC (up to 3m) or shorter AOC variants (MFS1S00-H005V, MFS1S00-H010V). Minimum Bend Radius: 35mm. Use figure-8 coiling for excess slack. Do not coil below 20cm diameter. Compatible With: NVIDIA Quantum HDR switches, Spectrum-2/3 Ethernet switches, ConnectX-6 VPI adapters with 200Gb/s PAM4 support. Predecessor: 100G QDR/FDR AOCs. Successor: 400G NDR AOCs (MFS1S50 series).
