Frequently Asked Questions
What is a 10GBASE-CU passive twinax cable used for?
A 10GBASE-CU passive twinax cable is used for short-distance, high-speed data center connections between servers, switches, and storage systems. It provides 10 Gigabit Ethernet performance over copper at distances up to 10 meters, making it ideal for in-rack and adjacent-rack deployments where fiber optics are unnecessary.
Is this SFP+ cable compatible with my Mellanox or Ruckus switch?
Yes. The ENET SFC2-MNRU-3M-ENC is specifically certified for Mellanox ConnectX adapters and Ruckus ICX switching platforms. It meets all OEM compatibility requirements and integrates seamlessly with existing infrastructure without additional configuration.
What are the advantages of passive DAC over active cables?
Passive direct attach cables eliminate power consumption, reduce heat generation, and offer superior reliability due to the absence of active electronics. They are also significantly more cost-effective than active DACs while delivering identical 10G performance for distances up to 10 meters.
How long is the 3-meter cable, and is it suitable for my deployment?
The 3-meter length is ideal for connecting adjacent racks, top-of-rack switches to servers, and storage arrays within the same data center row. For longer distances, consider fiber optic solutions; for shorter connections, 1M or 2M variants may be more appropriate.
