400G QSFP-DD QDD AC Active DAC Cable

The 400G QSFP-DD QDD AC Active DAC Cable, 5m is a active twinax direct attach copper cable with QSFP-DD, supporting 425Gbps links over a length of 5m (16ft). 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.

The 400G QSFP-DD QDD AC Active DAC Cable, 5m connects QSFP-DD ports at 425Gbps in 400G Ethernet data center and cloud network environments. This unit is manufactured in 4 standard lengths from 1m (3ft) to 5m (16ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Standards compliance covers QSFP-DD MSA, SFF-8636. The unit works in any equipment with a standard QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Part number of this model: QDD-400G-AC. Length options are 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

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.
