FAQ
What is the maximum data transfer rate of this DAC cable?
This Axiom DAC cable supports a maximum data transfer rate of 40 Gbit/s, compliant with the 40GBASE-CR4 Ethernet standard. It achieves this throughput by aggregating four lanes of 10 Gbit/s each across the twinaxial conductors, providing full 40 Gigabit Ethernet performance for short-reach connections between compatible network devices.
What devices is this cable compatible with?
The cable is designed for compatibility with network devices, routers, and switches that feature QSFP+ ports. It is specifically noted as Mellanox compatible, ensuring reliable operation with Mellanox network equipment. The 40GBASE-CR4 compliance provides standards-based interoperability with other QSFP+ enabled devices from various manufacturers in data center and enterprise environments.
What does 'passive' mean for this DAC cable?
Passive indicates that this direct attach cable does not contain active signal processing components like retimers or amplifiers. It functions as a pure electrical connection using copper twinaxial conductors to transmit data without requiring external power. This passive design reduces power consumption, heat generation, and cost compared to active cables while maintaining signal integrity across the specified 13.1-foot length.
How long is the cable and what is it suitable for?
The cable measures 13.1 feet (approximately 4 meters) in length, making it ideal for short-reach connections within data centers and enterprise networks. This length is well-suited for top-of-rack switching scenarios, server-to-switch interconnects within the same rack, and connections between adjacent racks. The twinaxial construction maintains 40 Gbit/s performance across this distance without signal degradation.
