400G QSFP-DD QDD ACxxx Active DAC Cable

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.

Product Highlights

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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

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. Samples for testing can be arranged before bulk orders.

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.

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.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
