Frequently Asked Questions
What is a 50GBase-CU direct attach cable used for?
A 50GBase-CU DAC is used for high-speed data center connectivity between switches, servers, and storage arrays over short distances (typically under 1 meter). It provides 50Gb throughput without the cost and complexity of active optical solutions.
Is this passive twinax cable compatible with my network equipment?
Yes, this cable features MSA-compliant SFP-DD connectors, ensuring compatibility with standard transceivers and network interfaces that support 50GBase-CU connectivity. Verify your equipment supports SFP-DD form factor.
What does TAA compliance mean for this direct attach cable?
TAA compliance indicates this cable meets Trade Agreements Act requirements, making it eligible for government and regulated procurement processes. It's manufactured and sourced according to federal acquisition standards.
Can I use this 0.5m cable for longer distances?
No, this passive twinax cable is rated for 0.5m maximum reach. For longer distances, consider active optical cables or repeaters. Using beyond rated distance may result in signal degradation and connection failures.
