Frequently Asked Questions
What is a passive DAC twinax cable and why should I use one?
A passive direct attach copper cable is a cost-effective alternative to active optical cables and transceivers. The 25GBASE-CU SFP28 passive DAC requires no power, generates minimal heat, and delivers full 25Gbps performance over short distances—perfect for data center rack interconnects and switch-to-server connections.
Is this SFP28 twinax cable compatible with my NetApp system?
Yes. This Axiom cable is specifically certified for NetApp compatibility and works seamlessly with NetApp switches, storage arrays, and compute nodes equipped with SFP28 ports. Always verify your hardware supports 25GBASE-CU before deployment.
What is the maximum distance for this 25GBASE-CU cable?
The 0.5m length is optimized for short-reach interconnects within data center racks and adjacent equipment. For longer distances, consider active DAC cables or optical transceivers rated for extended reach.
How does a passive twinax cable compare to optical solutions?
Passive 25GBASE-CU twinax cables offer lower cost, zero power consumption, and simpler deployment than optical solutions. However, they're limited to shorter distances (typically under 10 meters). For long-distance connectivity, optical transceivers are recommended.
