Digitus SFP28 25G 3m DAC Cable SFP28 to SFP28 Passive Direct Attach Twinaxial Network Cable for 25GBase Ethernet and Switches

The Digitus SFP28 25G 3m passive direct attach copper cable is engineered for high-speed 25GBase Ethernet environments. This shielded twinaxial cable features SFP28 male connectors on both ends and facilitates reliable data transmission between switches, servers, and other compatible network hardware without the need for external transceivers or additional power supplies. Designed for professional networking tasks, it supports high data transfer rates while maintaining low energy consumption and operational efficiency.

Advantages

This direct attach copper cable offers a cost-effective and energy-efficient solution for short-reach high-speed network connections. By eliminating the requirement for separate optical transceivers and patch cords, it reduces overall system complexity and lowers power consumption during operation. The robust shielded twinaxial design ensures reliable signal integrity, while the hot-plug-capable connectors allow for seamless installation and maintenance without disrupting the entire network infrastructure.

Suitable for

• Connecting 25G network switches within a rack
• Linking high-performance servers to core networking equipment
• Data center interconnections over short distances
• Enterprise telecommunications and data acquisition systems

This cable may not be suitable for long-distance network links exceeding three meters, as passive direct attach copper cables are physically limited to short-range connections. It is also not designed for environments requiring external fiber optic conversion or installations where network devices lack compatible SFP28 ports.

Key specifications

• Cable length: 3 m
• Cable type: Passive DAC twinaxial
• Data rate: Up to 25.88 Gbps
• Connector 1: SFP28 male
• Connector 2: SFP28 male
• Wire size: AWG 30
• Power consumption: 0.5 W
• Operating temperature range: 0 °C to 70 °C
• Compliance: SFF-8432 and MSA SFP28

To install the cable, ensure that both network devices are powered on or support hot-swapping according to system guidelines. Remove any protective dust caps from the SFP28 male connectors. Firmly insert each end of the twinaxial cable into the corresponding SFP28 ports on your switches or servers until the latching mechanism clicks into place. Disconnection is achieved by pulling the release mechanism and gently pulling the connector straight out of the port.

What to consider before purchase

• Verify that your network switches or servers feature compatible SFP28 ports
• Confirm that the three-meter length is sufficient for your physical rack layout
• Check manufacturer compatibility guidelines for optimal integration

For best performance, always route the twinaxial cable carefully to avoid sharp bends and ensure it operates within the specified temperature range of zero to seventy degrees Celsius.
