The 400G OSFP 8x 50G PAM4 Finned Top to 4x QSFP28 4x 25G NRZ Breakout AOC, 5m connects OSFP (IHS/Finned Top) to 4x QSFP28 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 400G Ethernet data center and cloud network environments. The standard length range runs from 1m (3ft) to 30m (98ft).

Applications
In 400G Ethernet data center and cloud network environments, the 400G OSFP 8x 50G PAM4 Finned Top to 4x QSFP28 4x 25G NRZ Breakout AOC, 5m provides a factory terminated 400Gbps link between OSFP (IHS/Finned Top) to 4x QSFP28 ports. This unit is produced in 9 standard lengths from 1m (3ft) to 30m (98ft). One port becomes 4x QSFP28, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
This product is designed and tested to comply with CMIS 4.0, SFF-8636, IEEE 802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, OSFP MSA, SFF-8661, SFF-8639. It plugs into any standards-based OSFP (IHS/Finned Top) to 4x QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The factory part number is OSFP-400G-4Q4XNAO. This cable is available in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft). Lengths outside the standard range are made to order in our factory. Samples for testing can be arranged before bulk orders.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
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.
