400G OSFP IHS/Finned Top to 4 x 100G QSFP28 Active Optical Breakout AOC

The 400G OSFP IHS/Finned Top to 4 x 100G QSFP28 Active Optical Breakout AOC is an active optical cable assembly with OSFP (IHS/Finned Top) to 4x QSFP28, carrying 400Gbps over Breakout 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 center and cloud network environments. Cable length: 1m (3ft)~30m (98ft).

Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP IHS/Finned Top to 4 x 100G QSFP28 Active Optical Breakout AOC carries 400Gbps between OSFP (IHS/Finned Top) to 4x QSFP28 interfaces. 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. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x 50G-PAM4 to Quad 4x 25G-NRZ modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Standards compliance covers CMIS 4.0, SFF-8636, IEEE 802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, OSFP MSA, SFF-8661, SFF-8639. The unit works in any equipment with a standard OSFP (IHS/Finned Top) to 4x QSFP28 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 (3ft)~30m (98ft) under part number OSFP-400G-4Q4xNAOxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.
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.
Reliability Control
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
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.
