One 400G QSFP-DD switch port fans out into two 200G QSFP56 legs, and each leg feeds one Spark at a full, unsplit 200G. The Spark's cage is QSFP112, which accepts a QSFP56 plug, and the Spark runs 200G as 4x50G PAM4 — exactly what each leg of this cable carries.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible with MikroTik CRS804-4DDQ and CRS812 QSFP56-DD ports (set speed=200G-baseCR4 on lanes 1 and 5).

Use this cable to fan a switch port out to two Sparks — never to fan a Spark out to two of anything.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen you need it, and when you don't.\u003c\/strong\u003e If your switch has a 400G port for every node — a MikroTik CRS804-4DDQ, for example — you can run one straight 200G QSFP56 DAC per Spark and skip breakout entirely. 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":48070234636449,"sku":"MCP7H60-W002","price":5383.5,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2216\/8673\/files\/MCP7H60-W002-NVIDIAMellanox-Compatible-400G-QSFP-DD-to-2x200G-QSFP56-Passive-Breakout-DAC-Cable-2m.png?v=1791962157","url":"https:\/\/www.foxti.com.br\/products\/mcp7h60-w002-nvidiamellanox-compatible-400g-qsfp-dd-to-2x200g-qsfp56-passive-breakout-dac-cable-2m","provider":"FoxTI","version":"1.0","type":"link"}
