NVIDIA Mellanox 800Gb/s Twin-Port OSFP DAC Cable 1m

The NVIDIA Mellanox MCP4Y10-N001 is an 800Gb/s twin-port OSFP direct-attach copper (DAC) cable designed for high-density, low-latency interconnect in modern data center fabrics. This 1-meter passive cable enables full-duplex 800 Gigabit Ethernet connectivity between compatible OSFP-equipped switches and NICs, supporting both Mellanox Spectrum-4 and NVIDIA Quantum-2 HPC networking platforms without requiring active electronics or external power.

The cable delivers ultra-low latency and minimal signal integrity challenges inherent to copper-based interconnects, making it ideal for rack-to-row or within-rack topologies where distance permits. Dual-port configuration allows simplified cabling architecture in symmetric fabric deployments, reducing per-connection footprint and installation complexity.

Target environments include AI/ML compute clusters, HPC centers, and enterprise data centers requiring 800G fabric capacity with deterministic performance characteristics and simplified operational management compared to optical alternatives.

Ideal for

• AI training cluster fabric interconnect between 800G-capable switches and GPU compute nodes
• High-performance computing (HPC) center node-to-spine connectivity for tightly coupled parallel workloads
• Data center fabric upgrades from lower-speed OSFP infrastructure to 800Gb/s without rearchitecting topology
• Low-latency financial services trading networks requiring sub-microsecond packet transit within rack structures
• Dense storage array interconnect to 800G-capable switching infrastructure in enterprise data centers
• Multi-tenant cloud provider fabric segments supporting isolated, high-bandwidth tenant workload isolation
