400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable
For short reach 400Gb/s links in 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable offers a factory terminated active twinax assembly with QSFP-DD to 4xQSFP56 connectors and a length of 3-7m. Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. The cable meets QSFP-DD MSA SFF-8679 SFF-8636.

Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable carries 400Gb/s between QSFP-DD to 4xQSFP56 interfaces. This unit is supplied at 3-7m. One port becomes 4xQSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Standards compliance covers QSFP-DD MSA SFF-8679 SFF-8636. The unit works in any equipment with a standard QSFP-DD to 4xQSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
This model is supplied at 3-7m under part number QDD-400G-4QACxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.
Tested Before Shipment
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.
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
