400G QSFP-DD to 8 x 50G SFP56 Passive Copper Breakout DAC Cable
The 400G QSFP-DD to 8 x 50G SFP56 Passive Copper Breakout DAC Cable provides a 400Gbps copper connection between QSFP-DD to 8x SFP56 ports with a cable length of 0.5m (2ft)~3m (10ft). 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 8 x 50G SFP56 Passive Copper Breakout DAC Cable connects QSFP-DD to 8x SFP56 ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is supplied at 0.5m (2ft)~3m (10ft). By fanning one port out to 8x SFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs QSFP-DD-8x 50G-PAM4 SFP56-50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, SFF-8432, IEEE 802.3bs-400GAUI-8, IEEE802.3cd-50GAUI-1, CMIS 4.0, SFF-8472. It plugs into any standards-based QSFP-DD to 8x SFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
This model is supplied at 0.5m (2ft)~3m (10ft) under part number QDD-400G-8SPCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~30AWG. Samples for testing can be arranged before bulk orders.
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.
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.
Customization Service
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.
