Product Features
Technical Overview
This Direct Attach Cable implements the QSFP+ form factor with twinaxial copper construction, supporting 40 Gigabit Ethernet per the IEEE 802.3ba standard. The cable features identical QSFP+ connectors on both ends, each housing 38 electrical contacts arranged in a compact, hot-pluggable interface.
The 24 AWG copper conductors provide optimal signal integrity for 40GbE transmission over the 5-meter length, with the twinax design offering superior EMI shielding compared to traditional twisted pair cables. The passive architecture eliminates the need for signal retiming or electrical-to-optical conversion, making this cable ideal for connecting switches, routers, and servers within the same rack or adjacent racks.
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 cable offers several distinct advantages for network infrastructure deployment. The passive twinax design provides significant cost savings compared to active optical solutions while maintaining full 40GbE performance for short-reach applications.
Cost-Effective 40GbE Connectivity
Eliminates the expense of separate transceivers and fiber optic cabling while delivering identical 40GbE performance for distances up to 5 meters.
- No transceiver modules required
- Lower total cost of ownership
- Simplified inventory management
Reliable Copper Performance
24 AWG copper conductors with twinaxial construction ensure stable signal transmission with minimal latency and packet loss.
- Superior EMI shielding
- Consistent electrical characteristics
- Durable mechanical construction
Compliance & Quality Assurance
Manufactured in the United States with TAA compliance for government and educational procurement, backed by a lifetime warranty.
- TAA compliant for federal contracts
- Lifetime limited warranty
- Quality manufacturing standards
Deployment / Use Cases
This QSFP+ Direct Attach Cable is specifically designed for data center and enterprise networking environments where high-speed, short-reach connections are required between network devices.
Typical deployment scenarios include connecting top-of-rack switches to servers within the same rack, linking adjacent switches in a data center fabric, or establishing high-speed interconnects between storage arrays and servers. The 5-meter length provides flexibility for equipment placement while maintaining signal integrity for 40GbE transmission.
Data Center Interconnects
Connect leaf and spine switches within the same rack or adjacent racks in spine-leaf architectures, providing low-latency 40GbE links for modern data center fabrics.
Server-to-Switch Connections
Establish high-bandwidth connections between servers and top-of-rack switches for applications requiring substantial network throughput, such as virtualization hosts, database servers, or high-performance computing nodes.

User Manual
FAQ
What is the maximum distance this QSFP+ Direct Attach Cable supports?
This cable supports distances up to 5 meters (16.4 feet) while maintaining full 40GbE performance. The passive twinax copper design is optimized for short-reach applications within data center racks or between adjacent racks, providing reliable connectivity without the need for signal regeneration.
Is this cable compatible with Dell Force10 networking equipment?
The cable is designed for compatibility with network devices supporting the QSFP+ interface standard. While specifically mentioned as compatible with Dell Force10 equipment in the product title, it should work with any networking device featuring standard QSFP+ ports, including switches, routers, and servers from various manufacturers.
What does 'passive' mean for this Direct Attach Cable?
Passive means the cable contains only copper conductors without any signal processing electronics. Unlike active optical cables that include electrical-to-optical conversion and signal retiming, this passive cable relies on the networking equipment's transceiver circuitry to drive signals across the copper medium, resulting in lower power consumption and reduced heat generation.
What is TAA compliance and why is it important?
TAA (Trade Agreements Act) compliance means this product meets the requirements of U.S. government procurement regulations, allowing it to be purchased by federal agencies, educational institutions, and other entities subject to these regulations. The cable is manufactured in the United States, ensuring it qualifies for contracts requiring TAA-compliant products.
Can this cable be used for 10GbE or 25GbE connections?
This cable is specifically designed for 40GbE connections using the QSFP+ interface. While some networking equipment may support backward compatibility modes, the cable is optimized for 40GbE operation. For dedicated 10GbE or 25GbE applications, cables specifically designed for those speeds with appropriate connectors would provide better compatibility and performance.
What type of warranty does this cable include?
The AddOn ADD-QFOQMU-PDAC5M comes with a lifetime limited warranty, providing long-term protection against manufacturing defects. This warranty reflects the product's quality construction and reliability for critical networking applications where cable failure could disrupt network operations.
