Why Choose This Product?

• 800Gb/s NDR capability – Provides the bandwidth class required by modern AI and HPC networking architectures.
• 5m deployment flexibility – Gives data-center teams more cable-routing distance than 3m or 4m variants.
• Active copper architecture – Offers a high-speed copper interconnect option for suitable short-reach deployments.
• NVIDIA-defined SKU – Simplifies sourcing, BOM creation, asset tracking and replacement procurement.
• OSFP connectivity – Aligns with supported NVIDIA high-speed NDR networking equipment.
• Purpose-built for NDR environments – Targets the demanding interconnect requirements of AI clusters, HPC and high-performance data centers.
• Avoids unnecessary optical deployment – For supported 5m copper links, an ACC can provide the required reach without moving to an optical cable architecture.
• Clear model differentiation – N005 is specifically the 5m MCA4J80 variant, helping buyers select the required physical reach.
