Key Features

SFP28 to SFP28 direct attach cable
25 GbE data path
1.5 m cable length
Twinaxial copper construction
Designed for short-reach interconnects
QNAP CAB-DAC15M-SFP28 MPN

Keep 25 GbE links tight, predictable, and cost-efficient in the rack with QNAP’s 1.5 m SFP28 twinaxial direct attach cable. This DAC is designed for short-reach connectivity where optical modules are unnecessary, helping reduce power draw, part count, and cable management overhead. At 1.5 m, it fits neatly between adjacent equipment or across a single rack segment, making it a practical choice for top-of-rack switching, server uplinks, and storage fabrics. The direct-attach copper design supports high-speed interconnects without the added complexity of separate transceivers and fiber patching. For infrastructure teams standardizing on 25 GbE, this cable offers a straightforward way to preserve port density and maintain clean physical layouts. It is a focused component, but one that matters: the right length, the right interface, and the right medium for short-distance performance where reliability and simplicity count.

Ideal For

Connect adjacent switches in a top-of-rack 25 GbE fabric
Link servers to a 25 GbE access switch in the same rack
Patch storage nodes to network equipment in short-reach deployments
Reduce optical module usage in dense data center cabinets

Why This Product

1Uses direct-attach copper instead of optical transceivers for short runs

Frequently Asked Questions

What devices does this cable connect?▾

It connects SFP28-equipped devices, typically switches, servers, or storage systems that support 25 GbE direct attach cabling.

Is this cable intended for long-distance runs?▾

No. At 1.5 m, it is intended for short-reach rack and adjacent-rack connections where DAC is the right fit.

Does this cable require separate transceivers?▾

No. Direct attach cables integrate the connection path, so separate optical transceivers are not required for the link.

Why choose DAC over fiber for this application?▾

For short 25 GbE links, DAC can reduce cost, power use, and cable-management complexity while keeping the connection simple.
