400G OSFP 4 x 100G PAM4 RHS/Flat Top to 400G QSFP-DD 8 x 50G PAM4 Active Optical AOC

Built for 400G Ethernet data centers, HPC and machine learning clusters, the 400G OSFP 4 x 100G PAM4 RHS/Flat Top to 400G QSFP-DD 8 x 50G PAM4 Active Optical AOC delivers 400Gbps between OSFP (RHS/Flat Top) to QSFP-DD interfaces over AOC fiber at 850nm. The integrated design removes the need for separate optical modules and simplifies sparing. Cable length: 1m~30m (3ft~98ft).

Applications
The 400G OSFP 4 x 100G PAM4 RHS/Flat Top to 400G QSFP-DD 8 x 50G PAM4 Active Optical AOC is a 400Gbps active optical cable for OSFP (RHS/Flat Top) to QSFP-DD connections in 400G Ethernet data centers, HPC and machine learning clusters. This unit is supplied at 1m~30m (3ft~98ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. 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-4x 100G-PAM4 QSFP-DD-8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: OSFP MSA, QSFP-DD MSA, CMIS 4.0, IEEE 802.3ck-400GAUI-4, IEEE 802.3bs-400GAUI-8. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
This model is supplied at 1m~30m (3ft~98ft) under part number QDD56-400G-O112RAOxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.
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.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
