NVIDIA Mellanox MFS1S00-H030V Active Optical Cable, 200Gb/s HDR InfiniBand and 200GbE Ethernet, QSFP56 to QSFP56, 30m: The MFS1S00-H030V is a 30-meter active optical cable (AOC) integrated assembly with two QSFP56 ends, transmitting 200Gb/s using 4 × 50Gb/s PAM4 lanes. It is a fixed-length factory-terminated assembly — it is not a transceiver paired with a detachable MPO patch cord, and it is not a passive copper DAC. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
At 30 meters, this AOC operates well beyond the practical reach of passive copper DACs (which top out near 2-3m at 200Gb/s) and is also typically more cost-effective than separate QSFP56 SR4 transceivers plus an MPO trunk for short runs. The cable is end-to-end factory-tested and hermetically sealed at both connectors, eliminating dirty fiber-end-face issues common with field-terminated optics. The active VCSEL-based optics use 850nm multi-mode fiber internally and provide complete EMI immunity — useful when routing near power distribution units or high-current bus bars.
Deployment & Use Cases
End-of-row 200G HDR / 200GbE links between top-of-rack switches and aggregation/spine layers; AI training cluster GPU node-to-fabric uplinks where racks are 10-30m apart; HPC compute-to-storage 200G interconnects spanning multiple cabinets; cross-row Quantum HDR fabric leaf-spine connections; and 200GbE Ethernet uplinks in Spectrum-2/Spectrum-3 spine deployments where copper cannot reach.
Technical Specifications

Compatibility & Constraints
Compatible with NVIDIA Quantum HDR InfiniBand switches (QM8700, QM8790) and ConnectX-6/ConnectX-6 Dx VPI/EN adapters operating at 200Gb/s. Compatible with NVIDIA Spectrum-2 (SN3000) and Spectrum-3 (SN4000) Ethernet switches when ports are configured for 200GbE. Requires ports configured for native HDR/200GbE; will negotiate down to 100Gb HDR100 if a port is forced to 100G. Not compatible with QSFP28 100Gb-only switch ports without rate fallback configuration. Not mechanically compatible with OSFP or QSFP-DD cages — those require different cable form factors. This is a fixed 30m assembly — length is not field-adjustable. Maintain minimum 50mm bend radius at the QSFP56 boots; observe normal optical cable handling practices (no kinks, no crushing).
