QNAP QSFP28 100GbE Break Out Four SPF28 25GbE Twinaxial Direct Attach Cable (4.9')

The QNAP CAB-DAC15M-Q28B4 is a direct attach cable designed to connect a 100GbE QSFP28 port to four separate 25GbE SFP28 ports. This 4.9-foot (1.5-meter) cable is built to support high-speed data transfer in environments where multiple 25GbE connections are needed from a single 100GbE interface. It works well with compatible NAS enclosures, storage arrays, and network switches that support these standards, making it a practical choice for data centers and enterprise networks aiming to optimize their infrastructure.

Thanks to its twinaxial construction, the cable offers reliable signal integrity and durability over short distances, which is typical for direct attach cables. This makes it a cost-effective option for linking devices within racks or between adjacent racks without the need for additional transceivers. Whether you are upgrading your storage network or expanding your switch connectivity, this cable provides a straightforward and efficient way to manage multiple 25GbE connections from a single 100GbE port.

This cable is especially useful for IT professionals and network administrators who need to maintain high throughput and low latency in their setups. Its compatibility with QNAP and other supported hardware ensures smooth integration and stable performance in demanding network environments.
