Specifications

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.

NVIDIA/Mellanox Compatibility and Factory Testing

The verification process combines digital identification with a live link test and diagnostic observation. Host model, hardware revision and software release are useful inputs because qualification behavior can change between platform generations; those details allow platform-specific requirements to be reviewed before the cable is packed. 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.

Interoperability and Configuration Checks

Check three layers before deployment: the host must accept the cable identification, the port must support the stated aggregate rate, and the lane configuration must match the attached interfaces. On breakout hardware, also confirm channelization and the mapping of every branch. These checks are particularly important when similar-looking ports operate at different speeds or under different firmware settings.

Ordering Information

Specify the OEM part number and fixed length, then provide the intended host configuration if the link uses channelized or breakout ports. Separate part numbers should be used for separate lengths. This gives the compatibility review enough information to check both the physical assembly and the intended operating mode. This page describes QDD-400G-AC05 in 5m (16ft); quote this exact reference and length together with quantity and the intended host platform.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.

Quality Assurance and Packaging

Functional inspection covers identification, link establishment and the condition of both connector assemblies. The cable is then protected against dust and connector damage and packed without sharp bends. Labels can include the customer reference and host-platform note when requested for a controlled deployment.
