NVIDIA Mellanox MFS1S50-H030E HDR Active Fiber Splitter Cable, QSFP56 to 2×QSFP56, 200Gb/s to 2×100Gb/s, 30m LSZH: This is a 30-meter active fiber splitter cable for InfiniBand HDR fabrics. The single QSFP56 source carrying 200Gb/s HDR breaks out to two QSFP56 destinations each operating at HDR100 (100Gb/s). NVIDIA P/N 980-9I45C-00H030. It is not a passive copper DAC, not a 1:1 point-to-point AOC, and not a 4-way splitter. Condition: Refurbished, tested and certified.
Engineering Context: The QSFP56 source carries full HDR 200Gb/s, which is split across two QSFP56 destinations each operating at HDR100 (100Gb/s). At 30 meters, copper DAC is not viable for HDR signaling — active optical fiber preserves signal integrity end-to-end. The cable is bus-powered from QSFP56 host ports and uses a Low Smoke Zero Halogen (LSZH) jacket for data center fire-safety compliance.
Deployment & Use Cases: Connecting an NVIDIA Quantum HDR switch QSFP56 port to two ConnectX-6 HDR100 adapters in a 2-way fan-out; doubling effective HDR100 port density across compute racks; AI training fabrics where one switch port serves two GPU servers at 100Gb/s; storage backbones for parallel filesystems over IB HDR.

Compatibility & Constraints: Compatible with NVIDIA Quantum HDR switches and ConnectX-6 HDR/HDR100 adapters on the QSFP56 ports. Not compatible with NDR (400G/800G) or EDR-only systems, not a substitute for a 1:1 QSFP56 cable, and not intended for QSFP-DD or pure-Ethernet 200GbE deployments. The two QSFP56 destination legs share a single QSFP56 source port and cannot be operated as separate physical cables.
