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.

Product Highlights

• QSFP-DD
• Data rate: 425Gbps
• Cable type: Active Twinax
• Length: 1m (3ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD ACxxx Active DAC Cable provides a factory terminated 425Gbps link between QSFP-DD ports. This unit is supplied at 1m (3ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

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.

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.

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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
