400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC
The 400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC connects QSFP-DD to 4x QSFP28 ports at 400Gbps over Breakout AOC fiber at 850nm. Because the optics are built into the cable ends, installation is plug and play with no separate transceivers to manage, and airflow inside the rack stays unobstructed. It is well suited to 400G Ethernet, data center interconnect and 5G transport networks. Cable length: Customized.

Applications
In 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC provides a factory terminated 400Gbps link between QSFP-DD to 4x QSFP28 ports. Ordered in customized lengths, it matches the actual rack geometry without slack. The breakout design lets one high speed port feed 4x QSFP28, which raises port utilization and simplifies cabling in dense rows. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs QSFP-DD-8x 50G-PAM4 QSFP28-4x 25G-NRZ 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-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
This cable is built to order in customized lengths. Our part number QDD-400G-4Q4xNAOxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements.
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.
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.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
