400G QSFP-DD QDD ACxxx Active DAC Cable
The 400G QSFP-DD QDD ACxxx Active DAC Cable provides a 425Gbps copper connection between QSFP-DD ports with a cable length of 1m (3ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 400G Ethernet data center and cloud network environments.

Applications
The 400G QSFP-DD QDD ACxxx Active DAC Cable connects QSFP-DD ports at 425Gbps in 400G Ethernet data center and cloud network environments. This unit is supplied at 1m (3ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, SFF-8636. It plugs into any standards-based QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
This model is supplied at 1m (3ft) under part number QDD-400G-ACxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 30AWG.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
