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.

High-Density Rack Integration

In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation.

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 assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. 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.

Quality Assurance and Packaging

Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together.

Ordering Information

Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. 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

Available stock is normally prepared for dispatch within one to three working days, while larger production requirements are scheduled with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
