400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m
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. Length options run from 1m (3ft) to 20m (66ft) as standard.

Applications
The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m is a 400Gbps active optical cable for QSFP-DD to 4x QSFP28 connections in 400G Ethernet, data center interconnect and 5G transport networks. This unit is made in 8 standard lengths from 1m (3ft) to 20m (66ft). One port becomes 4x QSFP28, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. 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
The part number for this assembly is QDD-400G-4Q4XNAO. We offer this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft) and 20m (66ft). Other lengths can be custom manufactured on request. Volume pricing is available for project quantities.
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.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
