The 400G QSFP-DD to 2 x 200G QSFP56 Active Copper Breakout DAC Cable is a active direct attach copper cable with QSFP-DD to 2 QSFP56, supporting 400Gbps 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, SFF-8679.

Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 2 x 200G QSFP56 Active Copper Breakout DAC Cable carries 400Gbps between QSFP-DD to 2 QSFP56 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. 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, SFF-8679. The unit works in any equipment with a standard QSFP-DD to 2 QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This model is supplied at 1m (3ft) under part number QDD-400G-2QACxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

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.

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.

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.
