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

The 400G OSFP 4 x 100G PAM4 RHS/Flat Top to 400G QSFP-DD 8 x 50G PAM4 Active Optical AOC is an active optical cable assembly with OSFP (RHS/Flat Top) to QSFP-DD, carrying 400Gbps over AOC 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 centers, HPC and machine learning clusters. 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 connects OSFP (RHS/Flat Top) to QSFP-DD ports at 400Gbps in 400G Ethernet data centers, HPC and machine learning clusters. This unit is supplied at 1m~30m (3ft~98ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
Standards compliance covers OSFP MSA, QSFP-DD MSA, CMIS 4.0, IEEE 802.3ck-400GAUI-4, IEEE 802.3bs-400GAUI-8. The unit works in any equipment with a standard OSFP (RHS/Flat Top) to QSFP-DD 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 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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
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.
