400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable

The 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable provides a 400Gb/s copper connection between QSFP-DD to 4xQSFP56 ports with a cable length of 3-7m. 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.

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable provides a factory terminated 400Gb/s link between QSFP-DD to 4xQSFP56 ports. This unit is supplied at 3-7m. The breakout design lets one high speed port feed 4xQSFP56, which raises port utilization and simplifies cabling in dense rows. 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-8679 SFF-8636. It plugs into any standards-based QSFP-DD to 4xQSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model is supplied at 3-7m under part number QDD-400G-4QACxxx. Other lengths of the same assembly can be produced on request. Samples for testing can be arranged before bulk orders.

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.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.

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.
