Ubiquiti UACC-DAC-QSFP28-0.5M, DAC cable, QSFP28, 100Gb / s, 0.5m

Fast connection in a compact installation

The Ubiquiti UACC-DAC-QSFP28-0.5M is a passive QSFP28 DAC cable designed for short-distance connections, especially where simple, organised communication between devices matters. Its 0.5 m length is ideal for setting up connections within a rack, while support for 40/100 Gigabit Ethernet lets you use it in environments where you need a fast, direct connection between compatible Ubiquiti devices.

Key benefits

• Passive DAC design - makes it easy to connect devices directly without additional intermediary modules.


• 0.5 m length - ideal for connecting equipment in the same rack.


• 40/100 Gigabit Ethernet support - lets you use the cable for high-speed network connections.


• Ubiquiti UniFi compatibility - makes it easier to choose a cable for supported switches.


• QSFP28 copper cable - provides a direct, short connection in network infrastructure.

For racks and short connections

This cable is designed for short connections between switches , for example when devices are installed in the same rack or in adjacent racks. This helps you reduce excess cabling and keep the installation tidy. The PVC jacket and 30 AWG cable gauge describe its construction, while the stated operating temperature range of 0 to 70°C indicates its suitability for typical server environments.

Use in Ubiquiti networks

The source information indicates that passive QSFP28 copper cables are suitable for internal telecommunications and data networks using Ubiquiti routing and switching products such as EdgeRouter , EdgeSwitch and UniFi Switch . You can therefore use the UACC-DAC-QSFP28-0.5M wherever you need a direct connection between compatible devices and want to use a solution designed for 100G transmission.

Cable performance specifications

The data also lists several features that help you assess ease of installation and operation. The minimum bend radius of 37 mm helps with cable routing, the 7 mm jacket thickness describes its construction, and the maximum power consumption of 2.5 W is important information when designing connections in a larger installation. This set of specifications helps you select the cable for a specific use without having to guess its properties.
