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":"200g-qsfp56-compatibility-guide-for-mellanox-platforms-download-detailed-compatibility-configuration-guides","title":"MCP1650-H001E30 Mellanox Compatible, 200G QSFP56 Passive DAC Cable - 1m","description":"\u003ch2\u003eNVIDIA\/Mellanox MCP1650-H001E30 200Gb\/s HDR QSFP56 Passive Direct Attach Copper (DAC) Cable - 1 Meter\u003c\/h2\u003e\n\u003cp\u003eThis NVIDIA\/Mellanox MCP1650-H001E30 is a high-performance 200Gb\/s QSFP56 passive twinax DAC cable, designed for short-reach, low-latency connections in InfiniBand HDR and 200GbE environments.
