The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Breakout AOC, 5m connects QSFP-DD to 2x QSFP56 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 and cloud network environments. We keep 9 standard lengths ready, running from 1m (3ft) to 30m (98ft).

Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Breakout AOC, 5m carries 400Gbps between QSFP-DD to 2x QSFP56 interfaces. This unit is offered in 9 standard lengths from 1m (3ft) to 30m (98ft). One port becomes 2x QSFP56, 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. The link runs QSFP-DD-8x 50G-PAM4 QSFP56-4x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with IEEE 802.3cd, IEEE 802.3bs, QSFP-DD MSA, SFF-8024, SFF-8679, SFF-8665, CMIS 4.0, OIF-CEI-04.0. It plugs into any standards-based QSFP-DD to 2x QSFP56 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-2QAO. Available lengths are 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft). If you need a length outside this list, our factory can build it to order.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
