Frequently Asked Questions
What is a 25G SFP28 DAC cable used for?
A 25G SFP28 DAC cable connects network switches, servers, and storage systems in data centers and enterprise environments. The passive copper design provides cost-effective, low-latency connectivity for 25 gigabit ethernet applications without requiring active electronics or external power.
What is the difference between passive and active DAC cables?
Passive DAC cables like this Axiom model use pure copper conductors and require no power, making them more economical and generating less heat. Active DAC cables include electronics for longer distances but consume power and cost significantly more. For short to medium-distance connections, passive copper DAC cables offer superior value.
How far can a passive copper SFP28 cable transmit?
Passive copper DAC cables typically support reliable transmission up to 7-10 meters depending on cable quality and environmental conditions. For longer distances, active DAC cables or optical transceivers are recommended. The Axiom 25G SFP28 cable is optimized for standard data center rack-to-rack and switch-to-server deployments.
Is this cable compatible with my network equipment?
The SFP28 to SFP28 connector configuration ensures broad compatibility with any network device featuring SFP28 ports, including Cisco, Arista, Mellanox, and other enterprise-grade switches and servers. Verify your equipment supports 25G SFP28 connectivity before purchase.
