Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable carries 400Gbps between QSFP-DD to 2 QSFP56 interfaces. Ordered in customized lengths, it matches the actual rack geometry without slack. The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

This product is designed and tested to comply with IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636. It plugs into any standards-based QSFP-DD to 2 QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This cable is built to order in customized lengths. Our part number QDD-400G-2QPCxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

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.
