Frequently Asked Questions
What is a 25GBase-CU direct attach cable used for?
A 25GBase-CU DAC is used for short-reach, high-speed connections in data centers, connecting switches to servers, storage systems, and other network equipment. The passive copper design makes it ideal for distances up to 3 meters where active optics would be unnecessary and costly.
Is this SFP28 cable compatible with my Brocade switch?
Yes, the Add-On 25G-SFP28-TWX-P-0301-AO is designed as a Brocade-compatible 25GBase-CU cable and provides certified interoperability with Brocade networking platforms. Verify your switch model supports 25GBase-CU SFP28 ports before deployment.
What are the advantages of passive copper over active optics?
Passive copper direct attach cables consume no power, generate minimal heat, have lower latency, and cost significantly less than active transceivers. For short distances (under 3 meters), passive copper delivers identical performance without the complexity or expense of active solutions.
Can I use this 3-meter DAC for longer distances?
No, the 3-meter specification is the maximum certified reach for this 25GBase-CU passive copper cable. For longer distances, consider active DACs or fiber optic solutions designed for extended reach.
