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.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports.
Juniper Networks Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. 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
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. 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
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag.
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. 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.
