The 400G QSFP-DD QDD ACxxx Active DAC Cable is a active twinax direct attach copper cable with QSFP-DD, supporting 425Gbps links over a length of 1m (3ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with QSFP-DD MSA, SFF-8636.

Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD ACxxx Active DAC Cable carries 425Gbps between QSFP-DD interfaces. 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. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Compliance: QSFP-DD MSA, SFF-8636. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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. Volume pricing is available for project quantities.
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
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.
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
