In 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 provides a factory terminated 400Gbps link between OSFP (RHS/Flat Top) to QSFP-DD ports. This unit is supplied at 1m~30m (3ft~98ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs OSFP-4x 100G-PAM4 QSFP-DD-8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

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.

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.

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.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

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.
