Ubiquiti Networks UACC-DAC-QSFP28-0.5M 0.5 m 100 Gbps QSFP28 direct attach cable

QSFP28 100 Gbps Direct Attach Cable

The Ubiquiti Networks UACC-DAC-QSFP28-0.5M is a half-metre QSFP28 direct attach cable rated for 100 Gbps maximum data rate. It provides a passive copper link between compatible network switches, routers or servers equipped with QSFP28 or QSFP+ ports. The 0.5 m length suits rack-adjacent connections where minimal cable slack is preferred.

Suitable for Short-Rack Interconnects

This cable fits administrators linking 100 Gbps or 40 Gbps ports inside a single rack or between neighbouring racks. It is not intended for runs that exceed the available length options, nor for environments that require optical transceivers for electrical isolation or longer reach. Buyers needing extended distances or fibre media should evaluate alternative solutions.

Passive Copper Behaviour Under Load

As a passive copper assembly, the cable maintains its rated 100 Gbps throughput without active signal conditioning or external power. Signal integrity remains stable across the 0.5 m span during sustained traffic, with latency and bit-error performance determined by the host ports' own equalisation. Heat contribution is negligible compared with active optical or active copper alternatives.
