Frequently Asked Questions
What is a 25GBASE-CU DAC cable used for?
A 25GBASE-CU DAC cable is used for direct, high-speed connections between network switches, servers, and storage arrays in data centers. It provides 25 Gigabit connectivity without the cost and complexity of active transceivers, making it ideal for short-distance, high-bandwidth applications.
Is this Mellanox-compatible DAC cable passive or active?
This cable is passive, meaning it contains no active electronic components or power requirements. Passive direct attach cables are more cost-effective and generate less heat than active alternatives, while delivering the same performance for distances up to 3 meters.
What devices are compatible with this 3M SFP28 cable?
This SFP28 passive cable is fully compatible with Mellanox switches, servers, and network interface cards that support 25GBASE-CU connectivity. It works with most enterprise-grade data center equipment featuring SFP28 ports.
How does a 25GBASE-CU DAC compare to fiber optic cables?
Direct attach copper cables offer lower latency, simpler deployment, and reduced cost compared to fiber optic solutions. However, they are limited to shorter distances (typically up to 5 meters). For longer distances or higher port density, fiber optics are recommended.
