400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable

The 400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable provides a 400Gbps copper connection between QSFP-DD to 2 QSFP56 ports with a cable length of Customized. As a passive cable it draws essentially no power and adds no latency to the link. 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.

Applications
The 400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable connects QSFP-DD to 2 QSFP56 ports at 400Gbps in 400G Ethernet data center and cloud network environments. Ordered in customized lengths, it matches the actual rack geometry without slack. 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 and Compatibility
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.
Ordering Information
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. Samples for testing can be arranged before bulk orders.
Packaging
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Quality and Testing
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.
