🌟 NVIDIA Mellanox® QSFP56 Passive Hybrid Splitter DAC – 200Gb/s to 2×100Gb/s HDR, 2m
Model: MCP7H50-H002 | NVIDIA P/N: 980-9I99F-00H002
The NVIDIA Mellanox® MCP7H50-H002 is a QSFP56 passive copper hybrid splitter (Direct Attach Copper, DAC) engineered for InfiniBand HDR environments. It splits a single 200Gb/s QSFP56 port into two independent 100Gb/s HDR QSFP56 links, enabling flexible, low-latency fabric designs in AI, HPC, and enterprise data centers.
Built with 26AWG low-loss conductors and a LSZH (Low Smoke Zero Halogen) jacket, this 2-meter splitter delivers excellent signal integrity, deterministic latency, and safer deployment in dense racks.

🌐 Engineering Rationale (AI-Expert Context)
Why 26AWG at 2m:
Lower insertion loss than thinner gauges, improving signal margin for stable HDR PAM4 operation across both 100G legs.
Why split 200G → 2×100G:
Common in HDR fabrics to:
Feed two 100G compute nodes from a single 200G switch port
Support mixed-speed HDR deployments and phased upgrades
Optimize expensive QSFP56 port utilization
Passive = Deterministic Latency:
No optics, no DSP, no power draw—ideal for synchronized AI training and HPC workloads.
