NVIDIA Mellanox MFS1S00-H050E QSFP56 InfiniBand HDR / 200GbE Active Optical Cable, 200Gb/s, 50m LSZH: This is a 50-meter active optical cable (AOC) with QSFP56 connectors on both ends, engineered for InfiniBand HDR and 200GbE point-to-point connectivity at 200Gb/s aggregate (4x 50Gb/s PAM4). The "E" suffix designates Ethernet support in addition to InfiniBand HDR. The assembly uses VCSEL optics over multi-mode fiber inside a Low Smoke Zero Halogen (LSZH) jacket. This is a fixed-length factory-terminated AOC, not a transceiver pair with separate patch cords, not a passive copper DAC, and not a hybrid splitter. This is a NEW unit supplied by T.E.S IT-SOLUTIONS.
Engineering Context
At 50 meters, MFS1S00-H050E covers cross-row HDR fabric runs that exceed the practical reach of 200G passive copper. Integrated VCSEL optics eliminate dirty fiber end-face issues common with discrete transceivers and MPO patch-cord pairings. PAM4 lane signaling at 50Gb/s per lane requires careful link-margin engineering, which the factory-terminated AOC delivers consistently. The cable is markedly lighter than copper, easing cable-tray load over long routes. Bit-error-rate target is below 1E-15 with FEC engaged. The LSZH jacket meets data center fire-safety codes.
Deployment & Use Cases
AI training and large language model clusters where ConnectX-6 HDR adapters connect to Quantum-1 (QM87xx) leaf or spine switches across rows. 200GbE Ethernet aggregation between Spectrum-2 (SN3000) switches and ConnectX-6 Dx EN adapters spanning a data hall. HPC fabrics requiring 25-50m HDR spans without splice trays. Storage front-end RDMA fabric on dual-mode (VPI) endpoints.
