Product Features
Technical Overview
This direct attach cable uses a passive electrical design, meaning it does not require external power or signal conditioning electronics. The twinaxial copper construction with 30 AWG conductors ensures efficient signal integrity over its 3-meter span, supporting the full 40 Gbit/s data rate specified by 40GBase-CU standards.
Each end terminates in a standard QSFP+ network connector, providing a direct interface to QSFP+ ports on switches, routers, or network interface cards. The cable is hot-pluggable, allowing for installation or replacement without powering down connected equipment. Its compatibility extends to Alcatel-Lucent and multiple OEM devices, making it a versatile solution for heterogeneous network environments.
Key Product Advantages
These strengths make the product easier to deploy and manage in real environments, especially where reliability, usability, and day-to-day operational continuity matter. Notable benefits include Cost-Effective Connectivity, Reliable Performance.
Cost-Effective Connectivity
Eliminates the expense of separate optical transceivers and fiber cables by providing a complete copper-based link solution for short-reach 40GbE connections.
- No separate transceivers needed
- Lower total cost than optical alternatives
- Simple plug-and-play installation
Reliable Performance
The passive twinaxial design ensures consistent 40 Gbit/s throughput with minimal latency, backed by a lifetime warranty for long-term reliability in demanding network applications.
- 40 Gbit/s data transfer rate
- Low-latency copper signal path
- Lifetime warranty support
Deployment / Use Cases
This QSFP+ direct attach cable is ideal for high-density data center environments where short-reach, high-speed interconnects are required. Common applications include linking top-of-rack switches to servers, connecting spine and leaf switches in Clos architectures, and establishing inter-switch links within a single rack or adjacent racks.
The 3-meter length suits scenarios where equipment is within close proximity, such as within the same rack or between neighboring racks. Its compatibility with Alcatel-Lucent and multiple OEM platforms makes it suitable for mixed-vendor deployments, reducing the need for vendor-specific cables. The TAA compliance also makes it appropriate for U.S. federal, state, and local government contracts requiring compliant networking components.

User Manual
FAQ
What is the maximum data transfer rate supported by this QSFP+ direct attach cable?
This cable supports a data transfer rate of 40 Gbit/s, which aligns with the 40GBase-CU Ethernet standard. It provides full duplex 40GbE connectivity between compatible QSFP+ ports on switches, routers, or network interface cards, making it suitable for high-bandwidth applications in data centers and enterprise networks.
How long is the cable, and what type of construction does it use?
The cable measures 9.8 feet (3 meters) in length and uses a twinaxial copper construction with 30 AWG conductors. This passive design ensures efficient signal transmission over short distances without requiring external power, providing a reliable and cost-effective solution for connecting nearby network equipment.
What does TAA compliance mean for this product?
TAA compliance indicates that this cable meets the requirements of the Trade Agreements Act, which governs U.S. government procurement. This means it is manufactured or substantially transformed in the United States or a designated country, making it eligible for use in federal, state, and local government contracts that require TAA-compliant networking components.
Is this cable active or passive, and what are the advantages of its design?
This is a passive direct attach cable, meaning it does not contain active electronics for signal conditioning or retiming. The advantages include lower cost, reduced power consumption, and simpler operation compared to active cables. It relies on the electrical properties of its twinaxial copper construction to maintain signal integrity over its 3-meter length at 40 Gbit/s speeds.
What warranty coverage does this product include?
The cable comes with a lifetime limited warranty from AddOn. This warranty covers defects in materials and workmanship for the life of the product, providing assurance of its durability and reliability in network deployments. The warranty terms are backed by the manufacturer's confidence in the cable's construction and performance.
