Frequently Asked Questions
What is a 25GBASE-CU DAC cable used for?
A 25GBASE-CU DAC (direct attach copper) cable provides high-speed 25 Gigabit Ethernet connectivity for short-distance data center interconnects. It connects network switches to servers, storage arrays, and other equipment within the same rack or adjacent racks, offering lower latency and cost than optical alternatives.
Is the Axiom SFP28 DAC cable compatible with my network switch?
The Axiom 25GBASE-CU SFP28 cable is compatible with any network equipment featuring SFP28 ports supporting 25GBASE-CU standard, including Cisco, Arista, Mellanox, and other enterprise switches. Verify your equipment specifications before purchase to ensure SFP28 port availability.
What is the maximum distance for this twinax cable?
This 2-meter passive DAC twinax cable is designed for short-distance connections up to 2 meters. For longer distances, consider active optical cables (AOCs) or separate transceiver modules with fiber optic cables.
Do I need transceivers with this direct attach copper cable?
No. The Axiom 25GBASE-CU DAC cable integrates SFP28 connectors directly into the cable assembly, eliminating the need for separate transceiver modules. Simply plug into compatible SFP28 ports for immediate 25Gb connectivity.
