This cable is the right answer when the switch has fewer 400G ports than you have nodes (such as the CRS812-8DS-2DQ-2DDQ, with only two QSFP-DD ports), or when you want to keep switch ports free to grow past four nodes. Either way, set the switch port speed to 200G manually rather than relying on auto-negotiation, and plan on MTU 9000 with both logical halves of each Spark port driven in parallel — a Spark port that is only half-loaded tops out near 100Gbps.\u003c\/p\u003e\n\u003cp\u003eNot sure whether your build needs breakout or straight cables? \u003ca href=\"\/pages\/dgx-spark-interconnect-reference\"\u003eSee the DGX Spark interconnect reference\u003c\/a\u003e or \u003ca href=\"\/pages\/request-a-quote\"\u003esend us your node count and switch model\u003c\/a\u003e and we will confirm exactly what to buy before you order.\u003c\/p\u003e\n\u003cp\u003eNeed different lengths, 4x100G breakouts, or bulk quotes? \u003cstrong\u003eContact us\u003c\/strong\u003e—we specialize in high-bandwidth breakout solutions for AI workloads.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e📋 COMPATIBILITY DOCUMENTATION\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eDownload comprehensive compatibility report: MCP7H60-W002_Compatibility_Report\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eGuide includes: Pre-tested compatibility matrix for NVIDIA Quantum-2 QM9700\/QM9790 switches, ConnectX-7 400G to ConnectX-6 200G breakout configurations, DGX Spark \/ GB10 switch-side breakout notes, EEPROM data and recognition protocols, QSFP-DD\/QSFP56 MSA compliance guidelines, fan-out implementation instructions.\u003c\/p\u003e","brand":"Resilient Tec","offers":[{"title":"Default Title","offer_id":47923345457252,"sku":"MCP7H60-W002","price":179.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/3482\/4548\/files\/nvidia-mellanox-compatible-mcp7h60-w002-400g-qsfp-dd-to-2x200g-qsfp56-passive-breakout-dac-cable-2m_1_b883d7c7-4468-433d-8aa9-15c146d9dced.jpg?v=1793196728"},{"product_id":"nvdgxspark-pb-nvidia-dgx-spark","title":"NVDGXSPARK-PB, NVIDIA DGX Spark 128GB","description":"\u003cp\u003eCondition: New\u003c\/p\u003e\n\u003cp style=\"border-left: 3px solid #1e8f5e; background: #f7f8fa; padding: 10px 14px; margin: 14px 0;\"\u003e→ \u003cstrong\u003e\u003ca href=\"\/pages\/dgx-spark-interconnect-reference\"\u003eDGX Spark interconnect reference\u003c\/a\u003e\u003c\/strong\u003e — approved stacking-cable part numbers, real-world throughput, and what to buy at two, three and four or more nodes.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThe DGX Spark is built around a single \u003cstrong\u003eGB10 Grace Blackwell Superchip\u003c\/strong\u003e that tightly integrates the CPU and GPU on one package.
