The 400G OSFP IHS/Finned Top to 4 x 100G QSFP28 Active Optical Breakout AOC connects OSFP (IHS/Finned Top) to 4x QSFP28 ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is supplied at 1m (3ft)~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. The link runs 8x 50G-PAM4 to Quad 4x 25G-NRZ modulation, which keeps it aligned with current 400G switch silicon.

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.

This model is supplied at 1m (3ft)~30m (98ft) under part number OSFP-400G-4Q4xNAOxxx. Other lengths of the same assembly can be produced on request.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

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.

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.

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.
