Frequently Asked Questions
What is a 25G passive DAC cable used for?
A 25G passive direct attach cable connects high-speed network equipment over short distances (typically up to 5-7 meters). It's commonly used for server-to-switch connections, switch-to-switch uplinks, and storage array interconnects in data centers where cost-effective, low-latency connectivity is essential.
Is this cable compatible with my Cisco network equipment?
Yes, the ADD-ON CISCO COMP DAC is specifically designed for Cisco-compatible infrastructure. It works with any Cisco switch, server, or storage device featuring standard SFP28 25G ports. Always verify your equipment supports 25G SFP28 transceivers before purchase.
What are the advantages of passive vs. active DAC cables?
Passive DAC cables like this model require no power, generate no heat, and cost significantly less than active alternatives. They're ideal for distances up to 5 meters. Active cables are needed for longer runs (7+ meters) but consume power and generate additional heat, making passive solutions more efficient for typical data center deployments.
Can I use this 5M cable for longer-distance connections?
This 5-meter passive twinax cable is optimized for distances up to 5 meters. For longer distances, consider active DAC cables or fiber optic solutions. Using passive cables beyond their rated distance may result in signal degradation and connection failures.
