Product Features
Technical Overview
This cable operates as a 40GBASE-CR4 compliant Active DAC, utilizing twinaxial copper construction to deliver 40 Gbit/s bandwidth across four lanes. The active electronics embedded in the cable assembly amplify and equalize the electrical signals, enabling reliable performance up to 23 feet without degradation, which exceeds the typical passive DAC reach for similar speeds.
The QSFP+ connectors provide a compact, high-density interface that supports the 40GBASE-CR4 standard, ensuring interoperability with Juniper QFX Series Switches and other compatible networking equipment. This design eliminates compatibility issues often associated with third-party optics, offering a plug-and-play solution for 40GbE connectivity.
Key Product Advantages
This Active DAC cable combines the cost-effectiveness of copper cabling with enhanced signal integrity, making it an optimal choice for short-reach 40GbE connections within racks or between adjacent racks in data center environments.
Enhanced Signal Integrity
Active electronics compensate for signal attenuation over the 23-foot length, ensuring stable 40 Gbit/s performance without errors or retransmissions.
- Reduces bit error rates
- Maintains consistent throughput
Juniper QFX Compatibility
Specifically coded for Juniper QFX Series Switches, this cable avoids compatibility warnings and ensures seamless integration with existing network infrastructure.
- Plug-and-play deployment
- No firmware adjustments needed
Cost and Power Efficiency
Compared to optical transceivers and fiber cables, this Active DAC solution lowers both initial hardware costs and ongoing power consumption while delivering equivalent 40GbE performance.
- Lower total cost of ownership
- Reduced power draw vs. optics
Deployment / Use Cases
This cable is ideal for connecting Juniper QFX Series Switches to other switches, routers, or servers within the same rack or across short distances in data centers. Its 23-foot length provides flexibility for cable management while maintaining high-speed 40GbE links.
Common applications include spine-leaf network architectures, high-performance computing clusters, and storage area networks where low-latency, high-bandwidth interconnects are critical. The active design ensures reliable performance in environments with electromagnetic interference or longer copper runs.
Data Center Inter-Rack Links
Connect Juniper QFX switches between adjacent racks for 40GbE spine-leaf topologies, leveraging the active electronics to overcome signal loss over 23-foot distances.
High-Density Server Connectivity
Link top-of-rack switches to servers or storage arrays within the same rack, providing cost-effective 40GbE throughput without separate transceivers.

FAQ
What is the difference between Active DAC and passive DAC cables?
Active DAC cables include embedded electronics that amplify and equalize signals, allowing longer reach (up to 7 meters for 40GbE) and better signal integrity compared to passive DAC cables, which are limited to shorter distances (typically 3-5 meters) due to signal attenuation without amplification.
Is this cable compatible with non-Juniper switches?
This cable is specifically coded for Juniper QFX Series Switches to ensure full compatibility and avoid system warnings. While it may physically connect to other QSFP+ ports, optimal performance and guaranteed interoperability are only assured with Juniper QFX Series devices as per the manufacturer's specifications.
What is the maximum data transfer rate supported by this cable?
This cable supports a data transfer rate of 40 Gbit/s (40 Gigabit Ethernet) as per the 40GBASE-CR4 standard. It utilizes four lanes of 10 Gbit/s each within the QSFP+ interface to achieve this aggregate throughput, suitable for high-bandwidth network applications.
