The NVIDIA/Mellanox Compatible 200G AOC OSFP Flat Top to QSFP56 Active Optical Cable is a high-performance hybrid active optical assembly designed for 200Gb/s InfiniBand (IB) HDR (High Data Rate) systems and high-density data center interconnects. Featuring an OSFP Flat Top / RHS (Riding Heat Sink) connector on one end and a QSFP56 connector on the other, this cable provides seamless cross-form-factor connectivity using 4x50G PAM4 optical channels over 850nm multimode fiber (MMF).

Engineered with a low-profile OSFP Flat Top design alongside a flexible LSZH (Low Smoke Zero Halogen) jacket, this cable allows easy routing in dense server racks with tight spaces. It is specifically optimized to interconnect 200G/400G NVIDIA ConnectX-7 OSFP SmartNICs (e.g., MCX75310AAS-NEAT, MCX755106AS-HEAT) directly to 200G HDR NVIDIA Quantum QM8700 / QM8790 and QM9700 / QM9790 InfiniBand switches. Fully compliant with OSFP MSA, SFF-8665 (QSFP56), CMIS 4.0, and 200G Ethernet protocols, it ensures low power consumption and reliable plug-and-play performance.

Key Features

  • Hybrid Form-Factor Architecture: Directly bridges an OSFP Flat Top / RHS interface to a QSFP56 port using 4x50G PAM4 modulation for 200Gb/s aggregate bandwidth.
  • Flat Top / RHS Design: Designed for servers and NICs requiring low-profile OSFP connectors without external integrated heatsinks.
  • Optimized NIC-to-Switch Interconnect: Perfectly tailored for connecting NVIDIA ConnectX-7 OSFP Network Interface Cards to Quantum HDR QSFP56 switches.
  • Flexible LSZH Assembly: Constructed with a Low Smoke Zero Halogen jacket and a tight 30mm minimum bend radius for high-density rack environments.
  • Power & Thermal Efficient: Consumes ≤10W on the OSFP end and ≤5W on the QSFP56 end, reducing overall cooling requirements.
  • Data Center Ready Compliance: Built to OSFP MSA and CMIS 4.0 specifications, fully compliant with IBTA Industrial BER standards and RoHS protocols.
