Product Features
Technical Overview
This direct attach cable operates at a data transfer rate of 40 Gbit/s, supporting 40 Gigabit Ethernet standards. The passive design means it requires no external power, drawing minimal power from the host device while providing stable electrical connectivity between QSFP+ ports.
The cable features QSFP+ connectors on both ends, each providing a single 40 GbE interface. Twinaxial copper construction ensures low latency and reliable performance for distances up to 4 meters, making it ideal for within-rack and adjacent-rack connections in data center environments.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Product Material, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
This direct attach cable offers several advantages over traditional fiber optic solutions, particularly for short-distance 40 GbE connections where cost and simplicity are priorities.

User Manual
FAQ
What is the maximum distance supported by this direct attach cable?
This QSFP+ direct attach cable supports distances up to 4 meters (13.1 feet). The passive twinaxial copper construction is optimized for short-reach applications within racks or between adjacent racks in data center environments, providing reliable 40 GbE connectivity without signal degradation at this length.
Is this cable compatible with Juniper Networks equipment?
Yes, this AddOn cable is designed as a Juniper Networks compatible direct attach cable. It is specifically coded for compatibility with Juniper QSFP+ ports and follows the 40GBase-CU standard for direct attach copper connections between compatible network devices.
What does 'passive' mean for this direct attach cable?
Passive means the cable contains no active electronic components or signal conditioning circuitry. It relies on the electrical properties of the twinaxial copper construction to transmit signals between QSFP+ ports. This results in lower power consumption, reduced heat generation, and typically higher reliability compared to active cables, though with distance limitations.
What applications is this 40 GbE direct attach cable best suited for?
This cable is ideal for 40 Gigabit Ethernet connections in data center environments, particularly for within-rack switch interconnects, server-to-switch links, and connections between adjacent racks. It's commonly used in spine-leaf architectures, high-performance computing clusters, and storage area networks where cost-effective short-reach 40 GbE connectivity is required.
What does TAA compliance mean for this product?
TAA (Trade Agreements Act) compliance indicates this product meets the requirements of U.S. government procurement regulations. Combined with its United States country of origin, this makes the cable suitable for federal, state, and institutional purchases where TAA compliance is mandated for networking equipment and components.
How does this direct attach cable compare to fiber optic solutions?
This copper direct attach cable offers a more cost-effective solution for short-distance 40 GbE connections (up to 4 meters) compared to fiber optic alternatives. It eliminates the need for separate optical transceivers, reduces power consumption, and simplifies deployment. However, fiber optics support much longer distances and are better suited for connections beyond a few meters or in environments with electromagnetic interference concerns.
