Product Features
Technical Overview
This DAC cable operates at a data transfer rate of 40 Gbit/s, utilizing the 40GBASE-CR4 standard to break out a single 40GbE QSFP+ connection into four independent 10GbE SFP+ channels. The twinaxial construction provides robust electrical signaling over copper, suitable for distances up to 5 meters where high-speed data transfer is required.
The cable features a QSFP+ connector on one end and four SFP+ connectors on the other, maintaining compatibility with network devices that support these interface types. Its passive architecture simplifies deployment by eliminating the need for signal conditioning or active components, reducing potential points of failure.

FAQ
What is the purpose of a QSFP+ to 4 SFP+ breakout cable?
This cable allows a single 40GbE QSFP+ port to connect to four separate 10GbE SFP+ ports, enabling high-density connectivity. It is commonly used in data centers to aggregate multiple 10GbE links into a 40GbE uplink, optimizing switch port utilization and reducing cabling complexity between network devices.
What does 'passive' mean for this DAC cable?
Passive indicates that the cable does not contain active electronic components for signal conditioning or retiming. It relies on the electrical properties of the twinaxial copper to transmit data over short distances, typically up to 5 meters. This results in a simpler, more reliable design with no external power requirements, making it a plug-and-play solution for compatible network equipment.
What types of network devices are compatible with this cable?
The cable is compatible with network devices that support QSFP+ and SFP+ interfaces, such as switches, routers, servers, and storage arrays. It is designed for use in standard 40GBASE-CR4 and 10GBASE-CU environments, ensuring interoperability with equipment from various vendors that adhere to these Ethernet specifications.
What is the maximum distance supported by this cable?
This cable supports a maximum distance of 5 meters (16.4 feet), which is typical for passive twinaxial DAC cables. It is suitable for short-reach connections within racks, between adjacent racks, or in close-proximity equipment setups where high-speed data transfer is required without the need for optical transceivers or fiber cabling.
