UniFi 100G Direct Attach Cable — QSFP28, 0.5 m
UACC-DAC-QSFP28-0.5M100 / 40 GbpsQSFP28 to QSFP28Passive copper · black
The Ubiquiti UniFi 100G Direct Attach Cable in 0.5 m (part number UACC-DAC-QSFP28-0.5M) is a passive QSFP28-to-QSFP28 copper cable carrying up to 100 Gbps between directly stacked aggregation switches, enterprise gateways and NVR-class hardware. It also runs at 40 Gbps with QSFP+-rate ports, needs no transceivers, and adds no power draw or heat. Typically in stock with fast delivery across Cyprus.
Compatibility note: Connects QSFP28 (100G) or 40G-rate ports; it does not split into 4×25G breakouts. The 7.0 mm jacket has a minimum 37 mm bend radius — at 0.5 m it suits directly adjacent devices only; use the 1 m or 3 m versions for longer in-rack runs.
Key Features
100G without transceivers
Integrated QSFP28 ends plug straight into both cages — the cheapest and lowest-latency way to move 100 Gbps between stacked UniFi devices.
Backwards compatible 40G
Auto-negotiates 40 Gbps when connecting older QSFP-rate ports, protecting the investment during staged upgrades.
Passive and cool
Zero power consumption and no optics to fail; black PVC jacket with 37 mm bend radius keeps the half-metre link tight and tidy.

Frequently Asked Questions
Singular Expert Insight
The 0.5 m QSFP28 DAC is the natural link between two aggregation switches stacked back-to-back — shorter is tidier and there is no signal penalty with passive copper. For anything beyond 3 m move to QSFP28 optics and fiber. See QSFP28-equipped models in our network switches range.
Buyer’s Guide
Buy it if
you are linking adjacent QSFP28 ports and want maximum throughput with zero configuration and zero power draw.
Skip it if
the ports are SFP28/SFP+ (use 25G/10G DACs) or further apart (use the 1/3 m versions or fiber).
Also consider
the 1 m or 3 m versions of this cable, or the UACC-Uplink-SFP28 series for 25G ports.
