Exact Length and Product Identity
This product page covers QDD-400G-AC05 in 5m (16ft). The OEM reference, physical length and HT factory configuration should remain together on the purchase order and receiving record. Other reaches or compatibility identities must be selected and verified separately rather than assumed to be interchangeable.
Cable Construction and Installation Planning
This 5m (16ft) active copper assembly connects compatible QSFP-DD ports without separate optical modules. Confirm the aggregate rate, lane configuration and host operating mode before installation. Support the complete twinax run, preserve connector access and do not crease the cable or force it into a tight service loop.
Project Documentation and Cable Identification
Large deployments are easier to audit when the order code, physical length and endpoint record agree. Keep the OEM reference in the compatibility document and use the HT part number on the packing list. Where several lengths arrive together, labels and carton groups can be arranged by rack or port plan so installers do not have to identify cables by appearance alone.
NVIDIA/Mellanox Compatibility and Factory Testing
Factory verification links the compatibility identity to the exact physical assembly described on this page. Identification, connector condition and live link behavior are checked before packing. Customers can submit equipment and firmware details with the project documentation for a more specific pre-order compatibility review. Factory acceptance covers both connector housings, host identification, live-link stability and diagnostic indications where the platform exposes them. The assembly is checked as the exact active copper configuration and length listed here.
Ordering Information
Use the listed HT part number for ordering and retain the OEM reference as the host-compatibility cross-reference. Send quantities by length, along with any rack-based packing or label instructions. If the project has mixed equipment, include the host model for each group rather than relying only on the aggregate cable rate. This page describes QDD-400G-AC05 in 5m (16ft); quote this exact reference and length together with quantity and the intended host platform.
Quality Assurance and Packaging
Inspection and link testing are completed before the cable enters its protective packaging. Project orders can be packed and labelled by length, rack or customer reference, with packing documentation that makes received quantities straightforward to reconcile against the installation schedule.
Shipping and Lead Time
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
