Specifications

Applications and Deployment

An AOC removes the separate module-and-fiber interfaces from a high-speed connection. Both optical ends remain attached to the cable, simplifying polarity control and connector handling. Host identification, wavelength plan, aggregate rate and any breakout configuration must still agree across the link. For this series, the listed interface is QSFP-DD to 8x 25G SFP28 and the aggregate rate is 200G.

Quality Assurance and Packaging

Each cable receives connector inspection and a functional link check before it is coiled with bend-safe slack and packed. Protective materials shield the connector housings during transport. Rack or project labels are available to keep length, part number and installation destination aligned. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.

Cable Construction and Routing

For this assembly, the minimum bend radius is 30mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is QSFP-DD <4W,SFP28 <1W. These parameters belong in the installation review rather than being treated as catalogue trivia. Route the cable through its intended managers without tension, avoid pressure close to the connector boots and leave enough space to operate the latches. Any service loop must respect the stated bend limit.

Data-Center Design and Airflow

Select the assembly by both reach and rack layout. A direct connection removes separate module-and-patch-cord interfaces, but it still needs a bend-safe pathway and clear connector access. Keep cable bundles from blocking front-panel airflow, account for the listed interface power where applicable and choose a length that supports maintenance without leaving an unmanaged coil. For this series, keep the interface rate, AOC construction and length-specific OEM reference together throughout that review.

Ordering Information

Provide the OEM reference, HT part number, fixed length and quantity, together with the intended host interfaces. Rack-based quantities and packaging instructions can be included for larger deployments. Other lengths are separate products and should be entered on their own order lines. For this series, follow the corresponding length link, quote that exact OEM part number and keep different lengths on separate order lines. HT part number AOC-Q28DD-8S28-25G identifies the product family; the linked page provides the final length-specific identity.

Dell Compatibility and Factory Testing

Compatibility confirmation combines host identification with actual link establishment and diagnostic checks. The assembly is prepared for the stated OEM reference rather than selected only by connector shape. For a new data-center deployment, the equipment model, port mode and software release provide the most useful basis for a pre-order review. Series-level inspection is followed by the exact length and OEM configuration selected for dispatch. Functional verification includes link establishment and diagnostic indications where the host exposes them.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
