Product Features
Technical Overview
This DAC cable operates on the 100GBASE-CR4 standard, utilizing four lanes of 25 Gb/s to achieve an aggregate bandwidth of 100 Gbit/s. The twinaxial copper construction provides robust signal integrity over its 3-meter reach, suitable for rack-level and adjacent-rack deployments in data centers or enterprise network closets.
The QSFP28 connectors are hot-pluggable, allowing for installation or replacement without powering down connected equipment, which minimizes downtime during maintenance or upgrades. The cable is engineered for low latency and low power consumption, contributing to efficient network performance and reduced operational costs.
Key Product Advantages
This cable offers several advantages for network administrators seeking reliable, high-speed connectivity solutions. Its passive design reduces complexity and cost compared to active optical cables, while the direct copper connection ensures consistent performance without the signal conversion delays associated with optical transceivers.
Cost-Effective High-Speed Connectivity
By using copper instead of fiber optics, this DAC cable provides a more affordable option for 100 Gb/s links over short distances, lowering total cost of ownership for network upgrades.
- Eliminates need for separate transceivers
- Reduces cabling and power costs
- Simplifies inventory management
Plug-and-Play Installation
The passive nature of this cable means no configuration or external power is required, allowing for quick deployment and minimal setup time.
- Hot-pluggable QSFP28 connectors
- No software configuration needed
- Compatible with standard QSFP28 ports
Deployment / Use Cases
This DAC cable is specifically designed for environments where high-bandwidth, low-latency connections are required between network devices in close proximity. Its 3-meter length makes it suitable for typical data center rack configurations where equipment is mounted within the same rack or adjacent racks.
Common deployment scenarios include connecting top-of-rack switches to aggregation switches, linking servers to leaf switches in spine-leaf architectures, and establishing high-speed interconnects between storage arrays and network fabric. The Juniper compatibility ensures seamless integration with Juniper Networks QFX series switches and other compatible network equipment, providing a reliable backbone for modern data-intensive applications.
Data Center Interconnects
Ideal for connecting switches and servers within data center racks, supporting high-throughput applications like virtualization, cloud computing, and big data analytics.
Network Infrastructure Upgrades
Enables cost-effective migration to 100GbE networks by providing simple, reliable cabling for new or existing network devices without requiring fiber optic infrastructure.

FAQ
What is the maximum data transfer rate supported by this DAC cable?
This Axiom DAC cable supports data transfer rates up to 100 Gbit/s using the 100GBASE-CR4 standard. It utilizes four lanes of 25 Gb/s each to achieve this aggregate bandwidth, making it suitable for high-speed network connections between compatible QSFP28 ports on switches, servers, or other network devices.
What does 'Juniper Compatible' mean for this cable?
Juniper Compatible indicates that this DAC cable has been tested and verified to work seamlessly with Juniper Networks equipment, particularly QFX series switches that feature QSFP28 ports. This ensures reliable performance and interoperability without requiring special configuration or causing compatibility issues in Juniper-based network environments.
What is the difference between passive and active DAC cables?
Passive DAC cables, like this Axiom model, use copper conductors without signal amplification electronics, making them simpler, more power-efficient, and typically more cost-effective for shorter distances (up to 3-5 meters). Active DAC cables include built-in electronics to boost signals, allowing for longer reaches but at higher cost and power consumption. This passive cable is ideal for rack-level connections where its 3-meter length is sufficient.
What types of network devices can I connect with this cable?
This cable is designed to connect any network devices equipped with QSFP28 ports, including switches, routers, servers, and storage arrays. The 'Network Device' specification indicates broad compatibility with standard 100GbE QSFP28 interfaces, making it suitable for data center, enterprise, and high-performance computing environments where 100 Gbit/s connections are required.
