Product Features
Technical Overview
This DAC cable utilizes a twinaxial construction, which provides superior signal integrity and electromagnetic interference (EMI) resistance compared to standard copper cables. The QSFP28 connector on one end breaks out to four SFP28 connectors on the other, enabling a single 100 GbE port to connect to four 25 GbE ports, optimizing port utilization and simplifying cabling.
The cable operates at 100 Gbit/s per the 100GBASE-CR4 standard, ensuring compliance with high-speed networking protocols. It is designed for use with OEM modules, switches, routers, and other network devices, supporting seamless integration into existing infrastructure.
Key Product Advantages
This cable delivers high-performance connectivity with minimal latency, essential for data-intensive applications such as cloud computing, storage area networks (SANs), and high-frequency trading. Its passive architecture eliminates the need for external power, reducing complexity and potential points of failure.
Enhanced Reliability
The twinaxial construction ensures durable, stable connections even in electrically noisy environments, maintaining data integrity over the cable's lifetime.
- Superior EMI resistance
- Consistent signal quality
- Robust physical design
Simplified Deployment
With pre-terminated connectors and a breakout configuration, this cable reduces installation time and minimizes errors compared to separate fiber optic modules and cables.
- Plug-and-play setup
- Reduced cable clutter
- Compatible with standard ports
Deployment / Use Cases
This cable is ideal for connecting top-of-rack (ToR) switches to servers or storage arrays in data centers, where high bandwidth and low latency are critical. It supports spine-leaf architectures by facilitating connections between aggregation switches and edge devices.
Common applications include linking 100 GbE switches to 25 GbE NICs in high-performance computing clusters, enabling efficient data transfer for virtualization platforms, and supporting network upgrades without replacing existing SFP28-capable equipment. Its Intel compatibility ensures it works with a wide range of branded networking solutions, providing flexibility in heterogeneous environments.

FAQ
What is the purpose of a QSFP28 to 4 SFP28 breakout cable?
This cable allows a single 100 GbE QSFP28 port to connect to four 25 GbE SFP28 ports, enabling efficient use of high-speed switch ports and simplifying cabling in data centers. It is commonly used to aggregate multiple lower-speed connections into a higher-bandwidth link, reducing port congestion and improving network scalability.
Is this cable compatible with Intel networking equipment?
Yes, the Axiom XXV4DACBL2M-AX is Intel compatible, meaning it is tested and verified to work with Intel-based switches, routers, and network interface cards. This ensures reliable performance and interoperability in environments using Intel hardware, though it may also function with other brands that support standard QSFP28 and SFP28 interfaces.
What does 'passive' mean for a DAC cable?
A passive DAC cable has no active electronics or signal conditioning components. It relies on the inherent electrical properties of the copper conductors to transmit data, resulting in lower power consumption, reduced heat output, and generally higher reliability compared to active cables. Passive cables are ideal for short-reach applications up to a few meters, like within a rack or between adjacent cabinets.
What types of devices can this cable connect?
This cable supports OEM modules, switches, routers, and various network devices equipped with QSFP28 and SFP28 ports. Typical use cases include connecting a 100 GbE switch to servers with 25 GbE network interface cards, linking storage arrays to network switches, or integrating high-performance computing nodes in a cluster environment.
