In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC provides a factory terminated 425Gbps (8x 53.125GGbps) link between QSFP-DD to 8x 50G SFP56 ports. This unit is supplied in 12 standard lengths from 1m (3ft) to 70m (230ft). The breakout design lets one high speed port feed 8x 50G SFP56, which raises port utilization and simplifies cabling in dense rows. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.

This product is designed and tested to comply with QSFP-DD MSA, SFP56 MSA, IEEE 802.3cd. It plugs into any standards-based QSFP-DD to 8x 50G SFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model carries part number QDD-400G-8SAO. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft), 30m (98ft), 50m (164ft) and 70m (230ft). Non-standard lengths can be produced on request. Samples for testing can be arranged before bulk orders.

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.

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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

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.
