QNAP CAB-DAC30M-SFP28 - Direct attach cable, 3 meters, Black

The QNAP CAB-DAC30M-SFP28 25GbE SFP28 Twinax Direct Attach Cable (3.0 m) is a network interconnect for high-speed wired environments. It uses SFP28 connectors on both ends to connect compatible hardware, such as NAS units and network switches. Data travels through this 3.0-metre cable at speeds of up to 25 Gbit/s. At 3.0 metres, the length is suitable for connecting devices within the same or adjacent equipment racks. Twinaxial copper wiring maintains performance over these short-distance paths.

As a passive direct-attach cable, it provides a reliable link without the power requirements or heat generated by active optical components. It is compatible with hardware featuring SFP28 ports, creating a secure physical connection for signal transfer. This cable eliminates the need for separate transceivers and fibre patches, simplifying network setup. The design is intended for 25GbE links in professional IT or advanced home lab environments, offering a low-latency solution for server nodes.

• Black finish: a neutral aesthetic that matches standard networking equipment.
• Direct-attach design: integrates connectors and transmission medium into a single, factory-terminated unit.
• Wired connectivity: provides a dedicated physical path for signal transmission between server nodes.
• Application: designed specifically for 25-Gigabit Ethernet deployments.
