Overview
The Ubiquiti UACC-DAC-QSFP28-0.5M-10 is a 10-pack of 0.5-meter direct attach copper cables for high-speed network interconnections. Each cable uses QSFP28 connectors on both ends and supports 100 Gbps and 40 Gbps data rates.
Connectivity
Each cable provides a direct QSFP28-to-QSFP28 connection and is compatible with QSFP28 and QSFP+ interfaces. The copper construction is intended for short-distance equipment interconnections where compatible high-speed ports are located close together.
Cable Construction
Each 0.5-meter cable uses 30 AWG copper conductors and a black PVC jacket with a 7 mm outer diameter. Ubiquiti specifies a minimum bend radius of 37 mm for the 0.5-meter cable.
Key Features
- 10 individual 0.5-meter QSFP28 DAC cables
- 100 Gbps maximum supported data rate
- 40 Gbps supported data rate
- QSFP28-to-QSFP28 connector configuration
- 30 AWG copper construction with black PVC jacket
Applications
The UACC-DAC-QSFP28-0.5M-10 is suited to short high-speed links between compatible switches, aggregation equipment, servers, and other network devices equipped with QSFP28 or QSFP+ ports. The 10-pack is useful for deployments requiring multiple short interconnections.
DC Supplies Product Note
Because these are 0.5-meter copper DAC assemblies, they are intended for short equipment interconnections; verify that both connected devices support the required QSFP28 or QSFP+ interface and data rate.
