Product Features
Technical Overview
This DAC cable adheres to the 100GBASE-CR4 Ethernet standard, supporting aggregate bandwidth of 100 gigabits per second over four lanes. The QSFP28 form factor provides a compact, high-density interface commonly used in modern data center switches and network appliances.
The twinaxial copper cable construction ensures robust electrical performance for distances up to 5 meters, making it suitable for top-of-rack switching, intra-rack connectivity, or adjacent equipment interlinks. The passive architecture eliminates the need for external power, simplifying deployment and reducing points of failure.
Key Product Advantages
The passive twinaxial design offers significant advantages in data center environments. It provides a durable, flexible cable that withstands repeated handling and routing within racks, while the lack of active components results in lower power draw and reduced heat generation compared to optical alternatives.
High-Speed Connectivity
Delivers 100 GbE throughput using the QSFP28 interface, enabling rapid data transfer for bandwidth-intensive applications like storage networking, virtualization, and high-performance computing clusters.
- 100 Gbit/s aggregate bandwidth
- QSFP28 form factor for density
- Low-latency copper transmission
Junior Ecosystem Integration
Designed for compatibility with Juniper network devices, ensuring reliable operation in Junos-based environments without requiring additional configuration or compatibility checks.
- Tested for Juniper platforms
- Plug-and-play installation
- Reduces interoperability risks
Deployment / Use Cases
This cable is ideal for scenarios requiring reliable, high-bandwidth connections over short distances. Common applications include linking top-of-rack switches to servers in hyper-converged infrastructure, connecting distribution switches in campus networks, or providing inter-switch links in enterprise core networks.
The 5-meter length provides flexibility for routing within standard 42U racks or between nearby equipment cabinets, while the passive design ensures compatibility with power budgets and thermal constraints in densely populated data center environments.
Data Center Interconnects
Connect Juniper QFX series switches to servers, storage arrays, or other network devices within the same rack or adjacent racks, supporting spine-leaf architectures and fabric expansions.
Network Infrastructure Upgrades
Migrate existing 40GbE links to 100GbE without replacing entire switch chassis, using QSFP28 ports to increase backbone capacity while maintaining copper cable plant investments.

FAQ
What is the maximum distance this DAC cable supports?
This passive twinaxial DAC cable is designed for distances up to 5 meters (16.4 feet). It maintains signal integrity for 100 GbE connections within this range, making it suitable for intra-rack or adjacent-rack deployments in data center environments.
Is this cable compatible with non-Juniper network equipment?
While specifically tested and coded for Juniper network devices, QSFP28 DAC cables often work with other vendors' equipment that supports the 100GBASE-CR4 standard. However, for guaranteed performance, use with Juniper platforms is recommended as compatibility with other brands may require verification.
What does 'passive' mean for this DAC cable?
Passive means the cable contains no active signal conditioning electronics. It relies on the electrical properties of the twinaxial copper to transmit signals, resulting in lower power consumption, reduced heat generation, and simpler deployment compared to active cables that include signal amplification or retiming circuitry.
Can this cable be used for 40GbE connections?
No, this cable is specifically designed for 100GbE (100GBASE-CR4) connections using the QSFP28 interface. It is not backward compatible with 40GbE QSFP+ ports, as the electrical signaling and lane configuration differ between the two standards.
