400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC

Built for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC delivers 425Gbps (8x 53.125GGbps) between QSFP-DD to 8x 50G SFP56 interfaces over OM3 fiber at 850nm. The integrated design removes the need for separate optical modules and simplifies sparing. Standard lengths run from 1m (3ft) to 70m (230ft).

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 available in 12 standard lengths from 1m (3ft) to 70m (230ft). One port becomes 8x 50G SFP56, 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 PAM4 modulation, which keeps it aligned with current 400G switch silicon.

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.

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. Volume pricing is available for project quantities.

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.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
