Frequently Asked Questions
What is a 25GBASE-CU SFP28 DAC cable used for?
A 25GBASE-CU SFP28 DAC cable connects high-speed network switches and servers in data centers. The passive copper design provides 25 Gbps connectivity over short distances (up to 3 meters) without requiring active electronics, making it ideal for cost-sensitive, high-performance networking environments.
Is this passive copper DAC compatible with Cisco and Mellanox equipment?
Yes. The ENET SF28C2-CIMN-3M-ENC is fully compatible with Cisco and Mellanox SFP28 ports. The standard SFP28 connector ensures seamless integration with both manufacturers' network infrastructure and switches.
What are the advantages of passive copper over active DAC cables?
Passive copper DAC cables eliminate power consumption, generate minimal heat, and reduce equipment strain compared to active alternatives. They are also significantly more affordable while delivering identical 25 Gbps performance for short-reach applications, making them the preferred choice for cost-optimized data center deployments.
Does this cable meet government procurement standards?
Yes. The ENET 25GBASE-CU SFP28 DAC is TAA (Trade Agreements Act) compliant, meeting U.S. government and federal procurement requirements for eligible products and services.
