Frequently Asked Questions
What is a 200GBASE-CR4 QSFP56 passive DAC cable used for?
A 200GBASE-CR4 QSFP56 passive DAC cable connects high-speed networking equipment in data centers, enabling 200 Gigabit Ethernet transmission between switches, servers, and storage systems over short distances. It's ideal for rack-level interconnects where low latency and cost-efficiency are critical.
Is this cable compatible with Mellanox switches and NICs?
Yes, the Axiom cable is fully compatible with Mellanox QSFP56-equipped networking devices. It supports standard 200GBASE-CR4 operation and has been verified for seamless integration with Mellanox infrastructure.
What are the advantages of a passive DAC cable over active alternatives?
Passive DAC cables consume zero power, require no external power supply, generate minimal heat, and have lower latency compared to active optical cables. They're more cost-effective for short-reach applications (typically under 5 meters) while delivering identical performance.
Can I use this 1-meter cable for longer distances?
No, this cable is specifically designed for 1-meter deployments. For longer distances, consider active optical cables (AOCs) or extended-length DAC solutions to maintain signal integrity and performance standards.
