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.

Rack Layout and Service Access

Plan the managed route before removing the connector protection. The cable should reach both ports without tension while leaving enough space to release the latches and service adjacent interfaces. Support the run through the intended managers, keep the connector boots clear of sharp edges and avoid storing excess length in a tight coil behind warm exhaust air.

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

Compatibility is verified as part of a complete installation check: connector inspection, host identification and an operating link. The physical cable is evaluated together with the expected OEM identity, because a connector that fits is not sufficient evidence that the host will accept and operate the assembly correctly. 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

The completed cable is inspected at both ends, functionally tested and coiled with bend-safe slack. Protective packaging keeps the latches and boots from taking impact, while optional project labels can identify the two endpoint locations for easier field service.

Ordering Information

When requesting this assembly, include the exact part number and length together with the destination port types. For a rack installation, a simple port-to-port list helps us keep different lengths separate and allows any requested labels to correspond with the actual installation sequence. 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. 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.
