FAQ
What is the maximum data transfer rate of this DAC cable?
This Axiom DAC cable supports data transfer rates up to 400 Gbit/s (400GbE) using the 400GBASE-CU standard. This high-speed connectivity is suitable for backbone network connections, data center interconnects, and other bandwidth-intensive applications where maximum throughput is required between compatible network devices.
What types of devices is this cable compatible with?
The cable is compatible with network switches, routers, and other network devices featuring QSFP-DD ports. It is specifically coded for Juniper network equipment, ensuring reliable operation and performance validation with Juniper switches and routers. The QSFP-DD connectors provide compatibility with next-generation high-density network equipment supporting this form factor.
What does 'passive' mean for this DAC cable?
A passive DAC cable contains no active electronics or signal conditioning components. This design eliminates the need for external power, reduces heat generation, and minimizes potential points of failure. Passive cables are typically more cost-effective than active alternatives and are ideal for short-distance connections where signal integrity can be maintained without amplification or retiming circuitry.
What is the cable length and type?
This cable measures 2.5 meters (8.2 feet) in length and uses twinaxial (twinax) copper construction. Twinaxial cable consists of two inner conductors surrounded by insulation and shielding, providing reliable signal transmission for high-speed data applications. The 2.5-meter length offers flexibility for within-rack or adjacent-rack connections in data center environments.
