Product Features
Technical Overview
This DAC cable operates at a data transfer rate of 40 Gbit/s, conforming to the 40GBASE-CR4 Ethernet standard for copper-based connections. It uses a twinaxial cable construction, which provides robust signal integrity and EMI protection suitable for environments requiring high-speed data transmission up to 10 meters.
The cable features QSFP+ male connectors on both ends, ensuring a secure physical interface with QSFP+ ports on network devices. Its passive twinaxial design means it relies on the host device's electrical signaling without active components, resulting in lower latency and power consumption compared to active optical cables or transceiver-based solutions.
Key Product Advantages
This cable delivers several practical benefits for network administrators and IT professionals. Its passive twinaxial construction ensures reliable performance with minimal signal loss, while the QSFP+ connectors provide a hot-pluggable interface that supports easy installation and maintenance without disrupting network operations.
Cost-Effective Connectivity
Eliminates the expense of separate optical transceivers and fiber cabling, offering a budget-friendly alternative for short-reach 40GbE links within racks or adjacent equipment.
- No transceiver modules required
- Lower total cost of ownership
- Simplified inventory management
Plug-and-Play Deployment
The passive design requires no configuration or external power, allowing for immediate use upon connection. This reduces deployment time and complexity in fast-paced IT environments.
- No software configuration needed
- Zero power draw from cable
- Hot-pluggable for live insertion
Deployment / Use Cases
This DAC cable is ideal for interconnecting network switches, routers, servers, and storage arrays in data center and enterprise settings. Its 2-meter length makes it suitable for top-of-rack switching, spine-leaf architectures, and high-density server farms where short-distance, high-bandwidth links are critical.
Common applications include linking Juniper QFX series switches, connecting to 40GbE uplink ports on aggregation switches, and establishing high-speed backplane connections in clustered computing environments. The cable supports high-throughput workloads such as virtualization, big data analytics, and media streaming that demand low-latency, reliable network performance.

FAQ
What is the maximum distance this DAC cable can support?
This passive twinaxial DAC cable is designed for short-reach connections up to 10 meters, with this specific model providing a 2-meter (6.6 ft) length. It is ideal for interconnecting devices within the same rack or adjacent equipment in data center environments.
Is this cable compatible with non-Juniper network equipment?
While engineered and coded for Juniper network devices, this QSFP+ DAC cable may work with other vendors' equipment that supports the 40GBASE-CR4 standard and QSFP+ interfaces. However, compatibility should be verified with the specific device manufacturer, as some platforms require vendor-coded modules.
Does this DAC cable require any special configuration or software?
No, this passive DAC cable requires no configuration or software setup. It is a plug-and-play solution that leverages the host device's electrical signaling. Simply connect the QSFP+ male connectors to compatible ports, and the link should establish automatically, making deployment straightforward.
