NVIDIA Mellanox MFA7U10-H010 400G HDR AOC Splitter Cable

The NVIDIA Mellanox MFA7U10-H010 is a 10-meter Active Optical Cable (AOC) splitter designed to connect a single 400Gb/s OSFP port with two separate 200Gb/s QSFP56 ports. It is built for HDR InfiniBand and 400GbE environments, making it useful when newer 400G OSFP infrastructure must interconnect with legacy 200G HDR/200GbE switch or HCA ports.

OVERVIEW

  • The MFA7U10-H010 is a 10m active optical splitter cable that converts one 400Gb/s OSFP connection into two independent 200Gb/s QSFP56 connections. Compatibility: designed for supported NVIDIA NDR/400GbE OSFP systems connecting to HDR/200GbE QSFP56 systems. Model comparison: H003, H005, H015, H020 and H030 provide 3m, 5m, 15m, 20m and 30m lengths. Choose H010 for 10m reach.

USE CASES

  • 400G-to-200G infrastructure migration - Connects a 400G OSFP system to two 200G QSFP56 ports, helping organizations integrate newer and legacy network generations.
  • HDR InfiniBand fabrics - Provides the required breakout topology for supported HDR deployments using 400G OSFP and 200G QSFP56 interfaces.
  • AI and GPU clusters - Useful where high-performance compute infrastructure needs to interconnect 400G-capable networking equipment with 200G HDR hosts.
  • HPC environments - Supports high-bandwidth connectivity between supported compute and fabric equipment without replacing every 200G endpoint.
  • 400GbE data-center networks - NVIDIA specifies support for connecting 400GbE OSFP switch ports to compatible 200GbE QSFP56 infrastructure. 
  • Legacy-to-modern network integration - The breakout architecture allows two 200G endpoints to be connected from a single 400G side.
  • Longer rack-to-rack connections - The 10m length provides substantially more routing flexibility than short DAC alternatives where equipment is separated across racks.
  • High-density networking deployments - A single OSFP connection branches to two QSFP56 connections, helping accommodate mixed-port infrastructure designs.

KEY FEATURES

  • 400Gb/s to 2 × 200Gb/s breakout - Enables one 400G connection to serve two 200G endpoints.
  • OSFP to 2 × QSFP56 - Connects different high-speed port form factors without requiring separate cable assemblies.
  • 10-meter optical reach - Provides additional routing flexibility for equipment positioned farther apart.
  • Active Optical Cable (AOC) - Uses an integrated optical cable assembly for the specified high-speed breakout application.
  • HDR InfiniBand support - Suits supported HDR networking environments requiring 400G-to-200G connectivity.
  • 400GbE support - Can be used in supported Ethernet deployments alongside InfiniBand applications. 
  • CMIS 4.0 OSFP management - Supports standardized management and monitoring functions on the OSFP end.
  • SFF-8636 QSFP56 management - Provides standardized management interface support on the two QSFP56 ends.
  • Digital Diagnostic Monitoring - Provides visibility into optical power, bias, voltage and temperature parameters for troubleshooting.
  • Hot-pluggable design - Simplifies installation and replacement during infrastructure maintenance.
  • LSZH/OFNR cable jacket - Provides a specified low-smoke, flame-retardant cable-jacket construction for data-center deployment.

Why Choose This Product?

  • Bridge 400G and 200G infrastructure - Helps organizations integrate newer 400G networking equipment with existing 200G endpoints.
  • Two 200G connections from one 400G port - Provides a purpose-built breakout topology for supported infrastructure.
  • 10m deployment flexibility - Gives data-center teams more freedom when switch and server locations are not adjacent.
  • Designed for AI/HPC networking - Supports the high-throughput interconnect requirements of supported GPU, HPC and data-intensive environments.
  • Integrated optical assembly - Reduces the need to separately source transceivers and fiber components for the specified connection.
  • Built-in diagnostics - Digital monitoring can assist network teams with operational visibility and fault isolation.
  • Multiple cable-length options - The MFA7U10 family offers several lengths, allowing procurement teams to match cable reach to rack topology rather than overbuying unnecessarily.
