Description
In the rapidly evolving landscape of artificial intelligence and high-performance computing, seamless high-speed interconnectivity is paramount. The NADDOD QSFP112 400G 0.5m Passive Direct Attach Copper (DAC) cable is engineered to meet these demanding requirements, offering a dedicated, high-density connection solution for the ASUS Ascent GX10 and NVIDIA DGX Spark platforms. By leveraging the advanced QSFP112 form factor, this cable delivers an aggregate bandwidth of 400Gbps over a short 0.5-meter distance, making it the ideal choice for adjacent server and switch clustering. Its passive design ensures near-zero latency and exceptional signal integrity without the power overhead associated with active optical components.
This high-performance interconnect solution is specifically designed to address the needs of specialized professionals and organizations:
- AI Infrastructure Engineers: Professionals deploying NVIDIA DGX Spark dual-system interconnects who require maximum throughput and minimal latency for distributed training workloads.
- Data Center Architects: System designers optimizing rack layouts for the ASUS Ascent GX10, seeking cost-effective, high-density cabling solutions for short-range links.
- Network Administrators: IT specialists managing high-speed enterprise networks who need reliable, plug-and-play NIC-to-NIC connections compliant with modern IEEE 802.3ck standards.
- HPC System Integrators: Engineers building custom high-performance computing clusters that demand rigorous compatibility testing and adherence to MSA standards.
- Enterprise IT Procurement Officers: Decision-makers looking for reliable, RoHS-compliant, and budget-friendly alternatives to expensive optical transceivers for short-reach 400G applications.
Built to rigorous industry standards, the technical specifications of this cable reflect its enterprise-grade construction:

Deploying the NADDOD QSFP112 400G DAC cable in a production environment reveals its immediate operational benefits. The hot-pluggable design allows for seamless integration into live systems without requiring downtime, while the robust PVC jacket and optimized bend radius of 37mm to 47mm facilitate clean cable management within crowded server racks. During high-throughput operations, such as large-scale AI model training or real-time data replication between DGX Spark systems, the cable maintains flawless signal integrity. Because it operates passively, it generates virtually no heat, significantly reducing the cooling load on the network switches and network interface cards (NICs) it connects.
When compared to Active Optical Cables (AOCs) or optical transceivers paired with fiber patch cords for short-range 400G connections, this passive copper cable offers distinct advantages. While optical solutions are necessary for distances beyond 7 meters, they introduce higher latency due to the electrical-to-optical conversion process and consume significantly more power—often up to 10W per link. The NADDOD QSFP112 DAC operates with a power consumption of less than 0.1W and introduces zero transceiver latency, making it both more energy-efficient and faster for sub-meter connections. Additionally, the passive copper architecture eliminates complex optical components, resulting in a lower total cost of ownership and a higher Mean Time Between Failures (MTBF).
To assist with deployment planning, here are answers to the most common technical inquiries regarding this interconnect:
- How does the compatibility of this cable extend beyond the ASUS Ascent GX10? While optimized for the ASUS Ascent GX10 and NVIDIA DGX Spark dual-system interconnects, it is fully compliant with the QSFP112 MSA and IEEE 802.3ck standards, ensuring compatibility with any standard-compliant 400G QSFP112 port.
- What are the power consumption specifications for this passive DAC? The cable operates passively and consumes less than 0.1W of power under normal conditions, with a maximum power draw of less than 0.25W, making it highly energy-efficient.
