Applications
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 in InfiniBand HDR fabrics, HPC clusters and AI computing networks. This unit is supplied at 3m~30m (10ft~98ft). The breakout design lets one high speed port feed 4x QSFP56, 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 OSFP-8x 50G-PAM4 QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE 802.3cd, CMIS 5.0, SFF-8661, SFF-8636. The unit works in any equipment with a standard OSFP (IHS/Finned Top) to 4x QSFP56 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
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
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.
Quality Assurance
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
