Dell AOC-Q56DD-400G Compatible 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable

Dell AOC-Q56DD-400G Compatible 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable

A 400G direct-attached link depends on the correct host identity, interface mode and physical length. This page covers the Dell AOC-Q56DD-400G compatible AOC series in QSFP-DD to QSFP-DD, including 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft), 30m (98ft), 50m (164ft), 70m (230ft) and 100m (328ft). Each documented length-specific OEM reference is linked separately where an individual product page is available.

Applications and Deployment

Active optical cables integrate optical engines and fiber into a single factory-terminated link. They provide a lighter, longer-reach alternative to copper direct attach without requiring separate transceiver and patch-cord selection. The complete assembly should be routed with bend protection and connected only between compatible optical standards and port modes. For this series, the listed interface is QSFP-DD to QSFP-DD and the aggregate rate is 400G. The stated application is 8x 50G-PAM4.

Dell Compatibility and Factory Testing

Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. 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.

Cable Construction and Routing

The specification table records the jacket material is OFNP; the minimum bend radius is 30mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is 8W Per End. Use those values when preparing the rack pathway and receiving checklist. Do not pull a connector by its cable, compress the run under tight ties or force excess length into a sharp coil. Connector protection should remain in place until the assembly is ready for insertion.

Structured Pathways and Serviceability

Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. For this series, keep the interface rate, AOC construction and length-specific OEM reference together throughout that review.

Ordering Information

Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. 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-Q56DD-400G identifies the product family; the linked page provides the final length-specific identity.

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.

Quality Assurance and Packaging

After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.

Frequently Asked Questions

Is this an original Dell cable?

No. It is an HT-manufactured compatible cable for equipment that specifies AOC-Q56DD-400G, not an original Dell-branded product.

Are different lengths and OEM part numbers separate products?

Yes. Where a length has its own OEM reference, follow the corresponding link above and order that exact part number on its own line. Do not substitute another length only because the connector arrangement is the same.
