The NVIDIA/Mellanox compatible 1m (3ft) 1.6Tb/s Twin-port OSFP224 to 2x 800G OSFP224 Passive Direct Attach Copper (DAC) Splitter Cable is engineered on 224G SerDes architecture for ultra-high-speed, short-reach interconnections. It enables splitting a single 1.6T OSFP224 Integrated Heat Sink (IHS / Finned Top) port into two 800G OSFP224 Riding Heat Sink (RHS / Flat Top) ports, providing a high-density, low-latency solution between 1.6T switches and 800G SuperNICs.

Designed as a passive direct attach copper cable, it provides an energy-efficient transmission path with near-zero power consumption (<0.1W) and ultra-low latency. It offers a cost-effective, high-bandwidth connection for next-generation data center backbones, enterprise HPC clusters, and InfiniBand XDR environments.

Key Features

• 1.6T to 2x800G Splitter Architecture: Converts a single 1.6T OSFP224 IHS port into two independent 800G OSFP224 RHS endpoints.
• 224G SerDes Technology: Built with advanced 8x200G PAM4 to 2x 4x200G PAM4 signaling architecture for high-density networking.
• Optimized Thermal Form Factor: Features an IHS (Finned Top) design on the 1.6T end and RHS (Flat Top) designs on the 800G ends for efficient rack heat management.
• Near-Zero Power Consumption: Operating power consumption is rated at less than 0.1W, maximizing energy savings in dense deployments.
• Data Center Ready: Fully compliant with InfiniBand XDR as well as 1.6T and 800G Ethernet industry standards.
