The Ubiquiti 100G Direct Attach Cable (DAC) is a high-performance, QSFP28-compatible cable designed for ultra-fast, short-reach connections directly between network switches, servers, and other compatible QSFP28 or QSFP+ interface devices. Sold in a convenient 10-pack, each cable measures 0.5 meters for optimal data center management and efficient rack cabling.

Key features include support for blazing data rates of up to 100 Gbps (also backward compatible with 40 Gbps via QSFP+), a durable black PVC jacket with approximately 7 mm outer diameter, and flexible 30 AWG wire gauge construction. Its minimum bend radius of about 37 mm ensures robust performance without signal degradation. The cable offers a low power consumption profile (~2.5 W max per unit) and operates reliably within an ambient temperature range from 0°C to 70°C.

This DAC eliminates the need for fiber transceivers or active optical cables, providing a cost-effective and reliable optical alternative for short-distance networking environments. Backed by a one-year manufacturer warranty, this cable is ideal for data centers, enterprise networks, and high-bandwidth server clusters requiring high-throughput, low-latency connectivity.
