## Summary description

Ubiquiti UACC-DAC-QSFP28-3M is a 3-meter direct attach cable with QSFP28 connectors on both ends for high-speed InfiniBand or fibre-optic compatible links. Designed for short-range interconnects between QSFP28 ports, it provides a simple, low-latency connection for switches, servers and adapters. Color: black.

## Long description

Ubiquiti UACC-DAC-QSFP28-3M is a 3-metre passive direct attach cable with QSFP28 connectors on both ends, supporting up to 100 Gbps data rates. It is intended for short-range, low-latency interconnects between QSFP28 or QSFP+ ports in switches, servers and network adapters. The cable has a black PVC jacket and is available in lengths from 0.5 m to 3 m.
Advantages
The cable offers a straightforward, low-latency connection for high-speed links up to 100 Gbps and is compatible with both QSFP28 and QSFP+ interfaces. Its PVC jacket provides basic mechanical protection for short-reach deployments and the fixed 3 m length simplifies installation in rack and data centre environments where short interconnects are required.
Suitable for
Short-range connections between QSFP28 or QSFP+ ports
Server-to-switch or switch-to-switch links in racks
High-throughput, low-latency applications such as storage clusters and HPC interconnects
When it may not be suitable
This passive DAC is designed for short-distance links; it is not suitable for long-haul connections or runs exceeding the available cable length (0.5–3 m). It also does not replace active optical cables for environments requiring extended reach, optical isolation, or fiber media.
Key specifications
Maximum data rate: 100 Gbps (also supports 40 Gbps)
Connector type: QSFP28 to QSFP28 (compatible with QSFP+)
Available lengths: 0.5 m to 3 m (this listing: 3 m)
Jacket material: Polyvinyl chloride (PVC)
Colour: Black
How to use
Power down or follow hot‑swap procedures recommended by your equipment vendor before insertion if required. Align the QSFP28 connectors with the ports and insert firmly until the latch engages. Verify link status on the connected devices and ensure firmware or driver compatibility if the link does not come up. Route the cable to avoid sharp bends and strain on the connectors; maintain the recommended bend radius for copper DACs.
What to consider before purchase
Required cable length for your rack or equipment layout (this product is 3 m)
Port compatibility (QSFP28 ports, or QSFP+ fallback support)
Whether a passive DAC meets distance and signal isolation needs versus active optical solutions
Environmental requirements for jacket material (PVC) and cooling considerations in dense racks
Usage recommendations
Use this QSFP28 direct attach cable for short, high-bandwidth links inside racks or between adjacent racks. Avoid exceeding the specified bend radius, and confirm compatibility with your switch or adapter firmware to ensure reliable 100 Gbps operation.
