Technical Overview

This DAC cable utilizes a twinaxial construction, which is optimized for short-distance, high-speed copper connections up to 10 meters. The passive design means it does not require external power, simplifying deployment and reducing power consumption compared to active optical cables or transceiver-based solutions.

The QSFP28 interface supports the 100GBASE-CR4 standard, providing four lanes of 25 Gb/s each to achieve the total 100 Gbit/s throughput. This makes it suitable for high-performance networking scenarios such as server-to-switch or switch-to-switch interconnects in modern data centers.

FAQ

What is the maximum data transfer rate of this DAC cable?

This Axiom DAC cable supports a data transfer rate of 100 Gbit/s (100 gigabits per second) using the 100GBASE-CR4 standard over its QSFP28 interface. This high-speed capability makes it suitable for bandwidth-intensive network applications in data centers and enterprise environments.

What does 'passive' mean for this DAC cable?

A passive DAC cable does not contain active electronic components for signal amplification or retiming. It relies on the electrical properties of the twinaxial copper conductors to transmit signals over short distances, typically up to 10 meters. This results in lower power consumption, reduced cost, and simplified deployment compared to active cables or optical transceivers.

What devices is this cable compatible with?

This cable is designed to be compatible with HP networking equipment that supports QSFP28 DAC cables. It can connect network devices, switches, and routers with QSFP28 ports, making it suitable for data center interconnects, server connections, and switch-to-switch links within HP-based network infrastructures.

What is the cable length and type?

The cable is 3 meters long, which equals approximately 9.8 feet. It uses a twinaxial (twinax) construction, which consists of two coaxial conductors twisted together within a single cable. This design is optimized for high-speed, short-distance copper connections with minimal signal interference.
