Ubiquiti QSFP28 DAC 100Gbps Cablu 0,5 m

Exact specifications

Use cases and applications

Use it for closely spaced equipment where the short 0.5 m routing length is sufficient and supported QSFP28 ports are available at both ends. Connector reach, strain relief and removal-tab access matter as much as the nominal cable length. No network-latency or application-throughput measurement is promised.

Compatibility and important limits

• Confirm QSFP28 DAC support, link mode and cable coding with both device manufacturers.
• Allow at least the specified 37 mm bend radius; a 0.5 m cable may be too short for routed or distant rack equipment.
• The SFP28 adapters in this range cannot accept this QSFP28 cable directly. No breakout function or included adapter is claimed.

Packaging and included items

One UACC-DAC-QSFP28-0.5M cable. The manufacturer also sells pack variants, but this listing is the single 0.5 m item, not a 10-pack. Switches and connector adapters are separate.

Image note: The manufacturer photo illustrates the QSFP28 cable family. The ordered item is the single 0.5 m UACC-DAC-QSFP28-0.5M; the family photo is not exact-length or multipack proof.

Optional accessories and alternatives

Accessories and alternatives are optional, not a required bundle. Check exact connectors, platform fit and supported media before combining products. Browse Cables for the wider range.

Packaging measurements

Estimated shipping package for quotation planning: 22 × 22 × 6 cm. Catalogue gross unit weight: 0.15 kg; this is not the bare-product mass. Package dimensions are a planning estimate, not a measured manufacturer specification. Confirm the final packed parcel before dispatch.

Dispatch and warranty

Dispatch within 48 hours. Dispatch and destination delivery are separate; stock is not reserved by viewing this page.

Warranty and service: 12-month return-to-base service. Ubiquiti’s separate limited manufacturer warranty for reseller-channel products is measured from its shipment to the authorised channel, not automatically from your Mineshop purchase date. Its two-year direct-webstore warranty does not apply simply because this cable is purchased online. Contact Mineshop to check the supplied unit’s entitlement.

How to start a claim: Contact Mineshop support with your order number, product serial number where present, a fault description and useful diagnostic photos. Wait for return authorisation and packing instructions before sending the product.

Commercial warranty and service terms do not limit your statutory rights against the seller. Physical damage, installation errors and use outside the manufacturer’s specifications are assessed under the applicable terms; no repair turnaround or advance replacement is promised.

Frequently asked questions

Is this one cable or a 10-pack?

This listing is the single-unit UACC-DAC-QSFP28-0.5M. Do not confuse it with a separately identified multipack.

Will it work with an SFP28 network adapter?

Not directly. QSFP28 and SFP28 are different connector form factors. The 25G SFP28 adapters in this range do not accept this cable.

Can the cable operate at 40G?

Ubiquiti lists 100 and 40 Gbps for the family. Both endpoints, firmware and negotiated link mode must support the chosen rate.

Does it split a 100G port into four 25G ports?

No breakout assembly is listed. This is a QSFP28-to-QSFP28 direct-attach cable, not a QSFP28-to-four-SFP28 cable.

What installation clearance is needed?

The 0.5 m variant has a 37 mm minimum bend radius. Check the connector bodies, routing and strain-relief space before ordering.

When is dispatch expected?

Dispatch within 48 hours. This is a dispatch estimate, not the arrival time. Delivery transit depends on destination and service.
