Mellanox MCP7H60-W003R30L 400GbE QSFP-DD to 4x100G QSFP28 Breakout AOC 3m

The Mellanox MCP7H60-W003R30L is a 400GbE to 4x100GbE active optical breakout cable engineered for high-performance data center interconnect in AI/ML GPU cluster environments. This 3-meter AOC (Active Optical Cable) provides a single 400G QSFP-DD connection on one end that breaks out to four independent 100G QSFP28 ports on the other, enabling flexible bandwidth distribution from high-capacity spine switches to multiple GPU compute nodes.

The breakout architecture eliminates the need for external optical transceivers, reducing component count and optical-to-electrical conversion overhead while maintaining signal integrity over extended reach. The 3-meter length accommodates mid-range intra-rack and short inter-rack connectivity scenarios where traditional direct-attach copper cables exceed power budgets or physical constraints.

Designed for modern cloud-native and HPC infrastructures, this cable supports non-blocking traffic patterns in scale-out GPU clusters, distributed training workloads, and consolidated storage-to-compute fabric architectures where 400G spine uplinks require granular distribution to multiple 100G-capable endpoints.

Ideal for

• GPU cluster interconnect: Distributing 400G spine switch bandwidth to four separate GPU node NIC ports in AI training farms
• High-performance computing: Connecting computational nodes in HPC clusters with long-reach optical breakout from centralized 400G fabric switches
• Data center AI/ML: Enabling efficient multi-node deep learning workloads with flexible 1:4 bandwidth splitting from aggregation layers
• Disaggregated storage-compute: Linking storage arrays with multiple 100G network ports to 400G fabric without external optics
• Inter-rack GPU connectivity: Extending 400G-to-100G reach beyond single-rack boundaries in multi-rack ML infrastructure
• Network fabric migration: Transitioning from 100G-only architectures to 400G cores while preserving existing 100G endpoint hardware
