The 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC connects QSFP-DD to 8x 50G SFP56 ports at 425Gbps (8x 53.125GGbps) over OM3 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. Standard lengths run from 1m (3ft) to 70m (230ft).

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 available 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. 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 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.

The standard part number of this assembly is QDD-400G-8SAO. We supply this cable 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). Custom lengths beyond this range can also be produced on request. Samples for testing can be arranged before bulk orders.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

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.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
