Dell AEC-Q56DD-400G Compatible 400G QSFP-DD 8 x 50G PAM4 Active Electrical Cable

Use this AEC cable where a 400G link is required between compatible QSFP-DD to QSFP-DD ports. This HT version corresponds to Dell AEC-Q56DD-400G and covers 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft); electrical or optical construction follows the AEC specification rather than a detachable transceiver-and-patch-cord arrangement.

AEC assemblies are intended for high-speed electrical links that require active signal recovery or retiming. Confirm host support, per-end power consumption and airflow, and keep both ends on the interface and breakout configuration stated in the specifications.

The QSFP-DD to QSFP-DD interface and 400G data rate must match the equipment at both ends. For breakout versions, confirm the lane mapping and the speed of every downstream port; matching connector shapes alone does not establish interoperability.

The assembly is configured for equipment that recognizes the AEC-Q56DD-400G series. Before shipment, we check connector identification, link establishment and electrical link stability, signal integrity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the switch, server or accelerator model and software release for a pre-order compatibility review.

This series is ordered by the base HT part number AEC-Q56DD-400G plus length and compatibility requirement. Available source configurations documented on this page are 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft); other lengths can be discussed with the factory with each length-specific OEM reference reviewed under its own product configuration.

Every AEC assembly undergoes continuity and link testing, compatibility verification and a visual inspection of both connector ends. Cables are coiled without exceeding their minimum bend radius, fitted with connector protection and packed in anti-static bags or protective trays before cartoning. Project labels and packing lists are available for volume orders.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
