400G OSFP 8 x 50G PAM4 IHS/Finned Top to 4 x 100G QSFP56 2 x 50G PAM4 Active Optical Breakout AOC

The 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 4 x 100G QSFP56 2 x 50G PAM4 Active Optical Breakout AOC connects OSFP (IHS/Finned Top) to 4x 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 InfiniBand HDR fabrics, HPC clusters and AI computing networks. Cable length: 3m~30m (10ft~98ft).

Applications
In InfiniBand HDR fabrics, HPC clusters and AI computing networks, the 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 4 x 100G QSFP56 2 x 50G PAM4 Active Optical Breakout AOC provides a factory terminated 400Gbps link between OSFP (IHS/Finned Top) to 4x QSFP56 ports. This unit is supplied at 3m~30m (10ft~98ft). By fanning one port out to 4x QSFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. 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 OSFP-8x 50G-PAM4 QSFP56-2x 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, CMIS 5.0, SFF-8661, SFF-8636. It plugs into any standards-based OSFP (IHS/Finned Top) to 4x QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
This model is supplied at 3m~30m (10ft~98ft) under part number OSFP-400G-4QAOxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
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.
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.
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.
