Frequently Asked Questions
What is a passive DAC cable and how does it differ from active cables?
A passive DAC cable uses direct copper connections without active signal conditioning, eliminating power requirements and latency. Unlike active optical cables (AOCs), passive DAC cables are more cost-effective for short distances (typically under 5 meters) and provide deterministic performance ideal for data center interconnects.
Is this QSFP56 cable compatible with Nvidia GPU systems?
Yes, this Axiom 200GBASE-CR4 QSFP56 cable is Nvidia-certified compatible, making it ideal for Nvidia DGX systems, HGX platforms, and GPU-accelerated data centers requiring high-bandwidth interconnectivity between compute nodes.
What are the maximum transmission distances for 200GBASE-CR4?
The 200GBASE-CR4 standard supports distances up to 5 meters for passive DAC cables. This 0.5-meter variant is optimized for ultra-short-reach applications within server racks and adjacent network equipment, ensuring maximum signal fidelity.
Can I use this cable for both server-to-switch and switch-to-switch connections?
Yes, the QSFP56 passive DAC cable supports both server-to-switch and switch-to-switch topologies. Its 0.5-meter length makes it particularly effective for high-density rack configurations where space efficiency and performance are critical.
