The 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC is an active optical cable assembly with QSFP-DD to 8x 50G SFP56, carrying 425Gbps (8x 53.125GGbps) over OM3 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 and cloud network environments. We keep 12 standard lengths ready, running from 1m (3ft) to 70m (230ft).

Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC carries 425Gbps (8x 53.125GGbps) between QSFP-DD to 8x 50G SFP56 interfaces. This unit is offered 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. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Standards compliance covers QSFP-DD MSA, SFP56 MSA, IEEE 802.3cd. The unit works in any equipment with a standard QSFP-DD to 8x 50G SFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
Order this assembly under part number QDD-400G-8SAO. Available lengths are 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). If you need a length outside this list, our factory can build it to order. 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.
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.
Reliability Control
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.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
