Cable Assembly : NVIDIA/Mellanox Compatible 800G (2x400G) Twin-port OSFP Finned Top to Twin-port OSFP Finned Top Passive Direct Attach Copper Cable (DAC), 8x100G PAM4 Modulation, Available in Lengths 0.5m (1.6ft), 1m (3ft), 1.5m (5ft), 2m (7ft), and 3m (10ft), 26AWG to 30AWG Wire Gauge, PVC Jacket, CMIS 5.0 Compliant, Finned Top / IHS Shells

The MCP4Y10-N002 (980-9IA0I-00N002 / OSFP-800G-CU2H) is an enterprise-grade 800Gb/s (2x400Gb/s) Twin-port OSFP to Twin-port OSFP Passive Direct Attach Copper Cable (DAC) engineered for ultra-dense AI clusters, High-Performance Computing (HPC) fabrics, and modern data center interconnects. Containing eight high-speed electrical copper pairs operating at up to 100Gb/s PAM4 per lane, this passive copper cable provides a cost-effective, zero-latency, and near zero-power (<0.1W) interconnect solution for short-reach rack deployments.

Equipped with Finned-Top / Integrated Heat Sink (IHS) OSFP enclosures at both ends, the MCP4Y10-N002 is specifically designed to provide optimal airflow and thermal management in air-cooled chassis layouts. It is natively optimized for linking 800G NDR / 1.6T XDR switches, such as 32-cage NVIDIA Quantum-2 (QM9700 / QM9790) and Spectrum-4 platforms, delivering high port density and maximum bandwidth with zero operational power overhead.

Key Features

• Ultra-Low Latency & Near Zero Power: Consumes less than 0.1W of power while providing direct physical layer connectivity for ultra-fast, low-latency AI training workloads.
• Dual Finned-Top Thermal Profile: Both connectors feature finned heat sinks tailored for air-cooled switch cages, ensuring efficient thermal dissipation in dense racks.
• 800Gbps Twin-Port Architecture: Operates 8 parallel electrical channels at 106.25Gb/s PAM4 to deliver 800G total throughput (2x400G logic).
• Multiple Length Configurations: Available in 0.5m (1.6ft), 1m (3ft), 1.5m (5ft), 2m (7ft), and 3m (10ft) options with 26AWG–30AWG wire gauges to suit flexible rack cabling layouts.
• 100% Verified NVIDIA Interoperability: Thoroughly validated with Quantum-2 switch systems, compliant with IBTA Industrial BER standards, OSFP MSA, CMIS 5.0, and RoHS.
• Robust Build Quality: Flexible PVC outer jacket with a strict 10x OD minimum bend radius for clean, high-density cable routing.
