NVIDIA Mellanox MCP7H50-series cable, P/N MCP7H50-H01A 1.5m Passive Copper Splitter Cable, 200Gb/s QSFP56 to 2x100Gb/s QSFP56: This is a 1.5 meters passive (un-amplified) direct-attach copper splitter cable that connects one 200Gb/s HDR QSFP56 port to two independent 100Gb/s HDR100 QSFP56 endpoints. It is not a QSFP28 100GbE cable, a QSFP-DD 400G cable, or an active optical cable. Sold as a new factory-sealed unit with NVIDIA P/N 980-9I98G-00H01A.
Engineering context: The MCP7H50 family uses 26 AWG twin-axial copper conductors and runs in passive PAM4 mode at 50 Gb/s per lane. The single QSFP56 head carries four 50 Gb/s PAM4 lanes (4x50G = 200Gb/s HDR); the two split QSFP56 heads each carry two 50 Gb/s PAM4 lanes (2x50G = 100Gb/s HDR100). Reach is matched to the 1.5m length; no retimer or DSP is present, so the host port's SerDes and FEC settings determine link margin.
Deployment and use cases: Top-of-rack to mid-rack 200Gb/s-to-2x100Gb/s aggregation in NVIDIA Mellanox Quantum HDR InfiniBand switches and Spectrum-2/SN3000 Ethernet switches; ConnectX-6 VPI and ConnectX-6 Dx HDR/HDR100 host adapters; leaf-spine HDR fabrics that need to feed two HDR100 hosts from one HDR switch port; RDMA workloads (GPUDirect, RoCEv2, NVMe-oF) in HPC and AI clusters; storage interconnects between QSFP56 endpoints.

Compatibility and constraints: Validated by NVIDIA for Quantum HDR InfiniBand switches, Spectrum-2/SN3000 Ethernet switches, and ConnectX-6 VPI/HDR host adapters in 200Gb/s-to-2x100Gb/s splitter mode. It will not operate as a 200Gb/s-to-200Gb/s straight cable, will not connect to QSFP28 (100GbE) ports as a single-port 100Gb cable, and is not a QSFP-DD 400G product. Switch ports must be configured for split/breakout mode and host NICs must support HDR100 (2x50G PAM4). Verify the part number against the vendor's qualified parts list before deployment.
