The MCP7Y50-N001 is an 800G OSFP to 4x200G OSFP passive breakout DAC cable built for next-generation AI clusters, hyperscale data centers, and NDR InfiniBand fabrics. It delivers 800Gbps aggregate throughput by splitting a single 800G OSFP port into four independent 200G OSFP connections — with zero active components, zero power draw, and zero latency overhead. Every unit is pre-programmed with EEPROM compatibility data and validated before shipment.
Will This Cable Work With My Platform?
Pre-coded for seamless plug-and-play recognition on:
-
NVIDIA Quantum-2 / NDR InfiniBand switches (QM9700 series and compatible)
-
NVIDIA Spectrum-4 Ethernet switches with 800G OSFP ports
-
NVIDIA DGX / HGX systems and GPU-to-switch interconnects
- Any OSFP MSA-compliant platform supporting 800GbE or NDR InfiniBand

Designed for AI & HPC Infrastructure
-
GPU cluster interconnects — spine-to-GPU or switch-to-DGX/HGX connections
-
NDR InfiniBand fabrics — 800G port breakout to 4x200G NDR endpoints
-
AI training and inference at scale — maximize throughput, minimize latency between nodes
-
Hyperscale data center leaf-spine — high-density 800G port utilization
-
High-throughput storage — NVMe over Fabric, GPUDirect Storage at 200G per lane
Common Mistakes This Cable Prevents
-
Buying AOC when DAC is sufficient — for 1-meter runs, passive DAC is lower cost, lower latency, and zero power
-
OEM-locked cables causing recognition failures — our EEPROM pre-coding eliminates firmware rejection
-
Wrong connector type — OSFP and QSFP-DD are not the same; always verify your port type before ordering
-
Latency spikes from active components — passive DAC has no signal processing, no added jitter
