NVIDIA Mellanox MFS1S00-H100E 100m HDR Active Optical Cable, QSFP56 to QSFP56, 200Gb/s: This is a 100-meter active optical cable (AOC) for InfiniBand HDR point-to-point interconnects and 200GbE Ethernet (VPI). The cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket. NVIDIA P/N: 980-9I44G-00H100. This is a fixed-length integrated assembly, not a transceiver pair with a detachable patch cord. This is a refurbished unit.
Engineering Context
The MFS1S00-H100E runs the InfiniBand HDR signaling layer at 4 lanes × 50Gb/s PAM4 across QSFP56. At 100m, it operates well beyond the passive-copper reach for HDR (which is limited to roughly 3m), making AOC the only practical option for this distance. The active optics maintain signal integrity end-to-end with negligible insertion-loss budget for the user; latency is the propagation delay across the fiber plus minimal optical-conversion overhead. The cable is lightweight versus copper and provides full EMI immunity. BER is rated below 1E-15. The LSZH jacket complies with strict data-center fire-safety codes.
Deployment & Use Cases
Cross-rack and cross-row 200Gb/s InfiniBand HDR fabric links between Quantum HDR switches and ConnectX-6 / ConnectX-6 VPI adapters in HPC and AI training clusters running NCCL, MPI, and SHARP workloads. Long-reach spine-to-leaf interconnects in multi-row data halls where the 100m length spans the topology. Where supported as VPI Ethernet: 200GbE backbone runs between Spectrum-2 switches and ConnectX-6 Ethernet adapters.

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Quantum HDR switches (QM8700, QM8790) and with HDR-capable ConnectX-6 / ConnectX-6 VPI adapters configured for HDR. Where the host port is configured as Ethernet, the cable supports 200GbE between Spectrum-2 switches and ConnectX-6 EN adapters; VPI mode must be set on both ends. Not compatible with EDR-only switch ports without HDR licensing. Not a breakout cable; this is a 1:1 QSFP56-to-QSFP56 assembly. Both endpoints must be configured for the same protocol (InfiniBand or Ethernet) and the same speed. Fixed 100m length.
