Frequently Asked Questions
What is a QSFP28 direct attach cable used for?
A QSFP28 direct attach cable connects high-speed networking equipment in data centers, including servers, switches, and storage arrays. The 100GBase-CU standard enables 100 Gbps connectivity over short distances with minimal latency, making it essential for modern cloud infrastructure and HPC environments.
Is this InfiniBand cable compatible with my Arista switch?
Yes. The AddOn Networks QSFP28-100GB-PDAC1MLZ-AR-AO is fully validated and certified for Arista Networks equipment. It meets all InfiniBand EDR specifications and works seamlessly with Arista 7050 series, 7060 series, and other QSFP28-equipped platforms.
What is the maximum distance for this 100GB passive copper cable?
This direct attach cable operates reliably up to 1 meter (3.3 feet). The passive copper design ensures zero latency and power consumption, making it ideal for rack-level interconnects where distance requirements are minimal.
Why choose passive copper over active cables?
Passive QSFP28 cables eliminate power consumption, heat generation, and potential failure points associated with active electronics. For distances under 5 meters, passive copper provides superior reliability, lower total cost of ownership, and easier troubleshooting in data center environments.
