Frequently Asked Questions
What is a 100GBase-CU QSFP28 passive DAC cable used for?
A 100GBase-CU QSFP28 passive DAC cable is designed for high-speed data center networking, enabling 100 Gigabit Ethernet connections between switches, servers, and storage systems over short distances (typically up to 5 meters). The passive twinax design eliminates the need for power, making it ideal for cost-sensitive, high-density deployments.
Is this cable compatible with my Arista or Mellanox equipment?
Yes, the AddOn ADD-Q28AR2Q28MX-P2M is fully compatible with both Arista Networks and Mellanox platforms. The dual OEM certification ensures seamless integration with these leading networking vendors' equipment without compatibility issues.
What are the advantages of a passive DAC over active alternatives?
Passive direct attach cables offer several benefits: zero power consumption, lower heat generation, reduced latency, simpler deployment, and significantly lower cost compared to active DAC cables. They're ideal for short-distance connections where signal integrity is maintained without active amplification.
Can I use this 2-meter twinax cable for longer distances?
The 2-meter length is optimized for short-distance data center interconnects. For distances beyond 5 meters, active DAC cables or fiber optic solutions are recommended to maintain signal integrity and performance standards.
