Technical Overview

This DAC cable operates on the 400GBASE-CU standard, utilizing twinaxial copper construction to achieve 400 Gbit/s throughput over a 3-meter distance. The QSFP-DD (Quad Small Form-factor Pluggable Double Density) connectors provide a high-density interface, supporting eight lanes of 50 Gb/s each for aggregate 400 Gb/s performance. The passive architecture means the cable does not include signal conditioning electronics, relying on the host devices for signal integrity, which simplifies design and reduces power consumption.

The cable's twinaxial design features two concentric conductors separated by insulation, optimized for high-frequency signal transmission with minimal interference. This construction ensures stable connectivity in demanding environments, such as data centers requiring consistent 400GbE links. The cable is hot-pluggable, allowing for installation and removal without shutting down network equipment, supporting maintenance and scalability with minimal disruption.

FAQ

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

This DAC cable supports a maximum data transfer rate of 400 Gbit/s (400GbE), utilizing the 400GBASE-CU standard over its twinaxial copper construction. It is designed for high-speed networking applications, providing sufficient bandwidth for data-intensive tasks like server interconnects, storage area networks, and high-performance computing environments.

Is this cable compatible with Juniper network equipment?

Yes, this DAC cable is Juniper compatible, meaning it is tested and verified to work with Juniper switches, routers, and other network devices that support QSFP-DD interfaces. This ensures reliable performance and interoperability in Juniper-based deployments, reducing compatibility concerns in mixed-vendor or upgrade scenarios.

What does 'passive' mean for this DAC cable?

Passive indicates that this DAC cable does not include active signal conditioning electronics, such as retimers or equalizers. It relies on the host devices to maintain signal integrity over the 3-meter length, which simplifies the cable design, reduces power consumption, and lowers cost compared to active cables. Passive DAC cables are ideal for short-reach connections where signal degradation is minimal.

What devices can I connect with this cable?

This cable is designed to connect network devices with QSFP-DD ports, including switches, routers, and network interface cards. It supports devices labeled for Switch, Router, and Network Device use, making it suitable for data center interconnects, enterprise network backbones, and high-performance computing clusters that require 400GbE links.
