FAQ
What is the maximum data rate supported by this DAC cable?
This cable supports 25 Gbps (gigabits per second) data rates using 25GBASE-CU technology over its twinax copper construction. It's designed for high-speed networking applications where 25 GbE provides optimal performance for server-switch connections and storage networking.
What does 'passive' mean for this DAC cable?
Passive means the cable contains no active electronic components for signal amplification or retiming. It relies on the inherent electrical properties of the copper conductors to transmit signals, resulting in lower power consumption, reduced heat generation, and simplified operation compared to active DAC cables that include signal conditioning electronics.
Is this cable compatible with Dell equipment?
Yes, this cable is specifically listed as Dell compatible, meaning it's designed to work with Dell servers, switches, and storage devices that feature SFP28 ports. This compatibility ensures reliable performance in Dell PowerEdge server and PowerSwitch network environments without requiring special configuration or causing compatibility issues.
What does TAA compliance mean for this product?
TAA (Trade Agreements Act) compliance indicates this cable meets U.S. government procurement requirements for products sold to federal agencies. It certifies the product is manufactured or substantially transformed in a TAA-designated country, making it suitable for government contracts, public sector deployments, and organizations with regulatory procurement requirements.
