Product Features
Technical Overview
This direct attach cable operates as a passive electrical connection, meaning it requires no external power or signal processing electronics. The twinaxial cable construction provides excellent electromagnetic interference shielding while keeping cable weight manageable at 9.6 ounces (272 grams).
The 0.5-meter (1.6-foot) length makes this cable ideal for connecting adjacent rack units or closely positioned networking equipment. The QSFP+ to 4xSFP+ configuration allows a single 40GbE port to connect to four 10GbE devices, providing efficient port utilization and simplified cable management.
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 alternative connectivity solutions for 40GbE deployments. The passive design eliminates power consumption concerns and reduces potential points of failure compared to active optical cables or transceiver-based connections.
Cost-Effective Connectivity
Provides 40GbE connectivity at a lower total cost of ownership than optical transceiver solutions, with no separate transceivers required.
- No transceiver purchases needed
- Lower power consumption
- Simplified inventory management
Reliable Performance
Copper twinax construction ensures stable electrical performance with minimal signal degradation over the 0.5-meter distance.
- 24 AWG gauge for signal integrity
- Twinaxial shielding against interference
- Consistent 40GbE throughput
Deployment / Use Cases
The ADD-QARSDE-PDAC50CM cable is specifically designed for short-reach 40GbE connections in data center and enterprise networking environments. Its 0.5-meter length makes it ideal for top-of-rack switching configurations where switches and servers are positioned in adjacent rack units.
Common deployment scenarios include connecting 40GbE QSFP+ switch ports to servers with SFP+ network interfaces, creating breakout connections for storage arrays, and establishing high-speed links between networking equipment in consolidated rack deployments. The cable supports network devices from various manufacturers that implement standard QSFP+ and SFP+ interfaces.
Physical Profile
This direct attach cable features a compact 0.5-meter (1.6-foot) length that minimizes cable clutter in dense rack environments. The copper construction with 24 AWG conductors provides durability while maintaining flexibility for routing through cable management systems. The cable weighs approximately 9.6 ounces (272 grams), contributing to reduced overall rack weight compared to longer or bulkier cabling solutions.

FAQ
What type of cable is the ADD-QARSDE-PDAC50CM?
The ADD-QARSDE-PDAC50CM is a passive direct attach cable (DAC) with twinaxial (twinax) copper construction. It features a QSFP+ connector on one end that breaks out to four SFP+ connectors on the opposite end, providing a 40GbE connection that distributes to four 10GbE ports. This cable type offers a cost-effective alternative to optical transceivers for short-distance connections.
What is the maximum data transfer rate supported by this cable?
This direct attach cable supports data transfer rates up to 40 gigabits per second (40 Gbit/s). The QSFP+ connector operates at 40GbE, while the four SFP+ connectors on the opposite end each support 10GbE connections. This configuration allows a single 40GbE port to connect to multiple 10GbE devices simultaneously.
How long is the ADD-QARSDE-PDAC50CM cable?
The cable measures 0.5 meters in length, which is approximately 1.6 feet. This short length makes it ideal for connecting equipment in adjacent rack units or closely positioned networking devices. The compact size helps minimize cable clutter and improves airflow in dense rack deployments.
What does 'passive' mean for this direct attach cable?
Passive means the cable contains no active electronics, signal processing components, or power requirements. It functions as a straight electrical connection between the QSFP+ and SFP+ connectors. This results in lower power consumption, reduced heat generation, and typically lower cost compared to active cables that include signal conditioning electronics.
Is this cable TAA compliant?
Yes, the ADD-QARSDE-PDAC50CM is TAA (Trade Agreements Act) compliant. This compliance makes the cable suitable for procurement by U.S. government agencies, educational institutions, and other organizations that require TAA-compliant products. The cable is also manufactured in the United States.
What warranty comes with this direct attach cable?
AddOn provides a lifetime limited warranty for the ADD-QARSDE-PDAC50CM direct attach cable. This warranty covers defects in materials and workmanship for the life of the product, offering long-term reliability assurance for network infrastructure deployments where cable failure could disrupt critical operations.
