The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m is an active optical cable assembly with QSFP-DD to 4x QSFP28, carrying 400Gbps over Breakout AOC at 850nm. Factory terminated and tested as a complete link, it offers a lighter and more flexible alternative to discrete transceivers with patch cords for 400G Ethernet, data center interconnect and 5G transport networks. We keep 8 standard lengths ready, running from 1m (3ft) to 20m (66ft).

Applications
In 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m provides a factory terminated 400Gbps link between QSFP-DD to 4x QSFP28 ports. This unit is offered in 8 standard lengths from 1m (3ft) to 20m (66ft). The breakout design lets one high speed port feed 4x QSFP28, 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.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, SFF-8661, IEEE802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. It plugs into any standards-based QSFP-DD to 4x QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Order this assembly under part number QDD-400G-4Q4XNAO. Available lengths are 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft) and 20m (66ft). If you need a length outside this list, our factory can build it to order. Samples for testing can be arranged before bulk orders.
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.
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.
Shipping and Lead Time
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.
