Product Features
Technical Overview
This cable operates at a data transfer rate of 40 Gbit/s, conforming to the 40GBASE-CR4 standard for efficient backbone and aggregation layer connectivity. The QSFP+ connectors on both ends support hot-pluggable installation, allowing for easy maintenance and upgrades without network downtime.
The passive DAC construction uses twinaxial copper cables to transmit electrical signals directly between devices, providing low latency and high reliability for distances up to 2 meters. This makes it ideal for top-of-rack switching, intra-rack connections, and short-distance interconnects where fiber optics would be unnecessary or cost-prohibitive.
Key Product Advantages
This DAC cable delivers several key benefits for network administrators seeking dependable, high-performance connectivity. Its passive feature ensures consistent operation without external power dependencies, enhancing reliability and reducing total cost of ownership.
Simplified Deployment
The pre-terminated QSFP+ connectors enable hassle-free setup, eliminating the need for separate transceivers and fiber splicing. This plug-and-play approach reduces installation time and minimizes configuration errors.
- No external power required
- Direct device-to-device connection
- Reduces cable clutter
Cost-Effective Performance
Compared to active optical solutions, this passive DAC cable offers a more economical option for short-reach applications while maintaining full 40 Gbit/s throughput. The lifetime warranty provides long-term peace of mind.
- Lower cost than AOC alternatives
- Lifetime warranty coverage
- Energy efficient operation
Deployment / Use Cases
This cable is specifically designed for environments where high-speed, short-distance connections between networking devices are required. Its Juniper compatibility makes it particularly valuable in data centers and enterprise networks utilizing Juniper switching infrastructure.
Common deployment scenarios include connecting top-of-rack switches to aggregation switches within the same rack, linking routers to core switches in server rooms, and establishing high-speed interconnects between network appliances in compact installations. The 2-meter length is optimal for these applications while avoiding excess cable management issues.
Data Center Interconnects
Ideal for connecting switches within the same rack or adjacent racks in data center environments, providing reliable 40GbE backbone connectivity without the complexity of fiber optics.
Enterprise Network Upgrades
Enables cost-effective migration to 40GbE networking for businesses upgrading their infrastructure, particularly those with existing Juniper equipment that requires compatible high-speed cabling.

FAQ
What is the maximum data transfer rate of this DAC cable?
This cable supports a maximum data transfer rate of 40 Gbit/s, conforming to the 40GBASE-CR4 standard. This provides sufficient bandwidth for high-speed network backbone connections, aggregation links, and data-intensive applications between compatible routers and switches.
Is this cable compatible with Juniper networking equipment?
Yes, this DAC cable is specifically designed for Juniper compatibility. It will work with Juniper routers and switches that support QSFP+ interfaces and 40GBASE-CR4 connections. Always verify compatibility with your specific Juniper model before deployment.
What does 'passive' mean for this DAC cable?
Passive means the cable does not require external power or signal conditioning electronics. It uses twinaxial copper conductors to transmit electrical signals directly between devices. This results in lower cost, higher reliability, and simpler deployment compared to active DAC or AOC cables, though with shorter maximum distance capabilities.
What is the cable length and what applications is it suited for?
The cable is 2 meters long (approximately 6.6 feet). This length is ideal for short-reach applications such as connecting devices within the same rack, top-of-rack to aggregation switch links, or router-to-switch connections in compact data center and enterprise environments.
