## Summary description

The Intel XXV4DACBL2M compatible Breakout Direct Attach Cable (DAC) is a passive 100 Gigabit to 4x25 Gigabit Twinaxial copper cable. It features a QSFP28 connector on one end and four SFP28 connectors on the other, allowing for high-speed connections between hardware in racks and across adjacent racks. With a length of 2 meters, this black cable is ideal for data centers requiring efficient and reliable connectivity.

## Long description

The Network Cable BlueLAN XXV4DACBL2M QSFP28 to 4xSFP28 100G 2M Black is a passive breakout direct attach cable designed for short-reach, high-bandwidth connections in data centers and enterprise networks. It converts a single 100G QSFP28 port into four independent 25G SFP28 links using twinaxial copper, enabling aggregation or breakout between switches, servers and storage systems. The 2 meter length and black jacket provide a practical option for in-rack and adjacent-rack cabling where low latency and link stability are required.
Advantages
This passive DAC offers low power consumption since no active electronics are required, and it delivers reliable signal integrity for short-distance, high-speed links. The breakout design simplifies port utilization by providing four 25G endpoints from one 100G port, reducing the need for additional transceivers and fiber patching. The cable's fixed length and robust twinax construction ensure consistent performance and easy installation in dense rack environments.
Suitable for
Connecting a 100G QSFP28 switch port to four 25G SFP28 server or switch ports
Top-of-rack and leaf-spine architectures in data centers
High-performance computing clusters requiring short, low-latency links
Intra-rack and adjacent-rack cabling where fiber is unnecessary
Key specifications
Connector configuration: QSFP28 to 4 × SFP28
Aggregate data rate: 100 Gigabit (4 × 25G breakout)
Cable type: Twinaxial copper (passive DAC)
Length: 2 meters
Jacket color: Black
Intended reach: Short-reach/in-rack and adjacent-rack
How to use
Insert the QSFP28 plug into the 100G port and connect the four SFP28 plugs to the corresponding 25G ports on servers or switches. Ensure both ends are fully seated and that connected equipment supports passive DAC breakout cables and the target link speeds. No external power or configuration is required for the cable itself; link negotiation and speed settings are managed by the connected devices. Route the cable to avoid sharp bends and secure it in the rack to prevent strain on connectors.
Usage recommendations
Use this cable for short-distance, high-throughput connections inside racks or between adjacent racks. Verify compatibility with your switch and server vendor before deployment, and maintain bend radius and strain-relief best practices to preserve signal integrity and connector longevity.
