Applications and Deployment

AOC assemblies integrate the optical engines and fiber into a single factory-terminated link. They are useful for longer or lighter high-speed connections than copper direct attach, with no fiber polarity or connector cleaning required between separate patch cords and modules.

The OSFP (IHS/Finned Top) to 4x QSFP56 interface and 400G data rate must match the equipment at both ends. The source application is listed as 400G to 4x 100G. For breakout versions, confirm the lane mapping and the speed of every downstream port; matching connector shapes alone does not establish interoperability.

NVIDIA/Mellanox Compatibility and Testing

The assembly is configured for equipment that recognizes the OSFP-400G-4QAO series. Before shipment, we check connector identification, link establishment and optical link operation, receive activity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the switch, server or accelerator model and software release for a pre-order compatibility review.

Ordering Information

This series is ordered by the base HT part number OSFP-400G-4QAO plus length and compatibility requirement. Available source configurations documented on this page are 30m (98ft); other project lengths can be discussed with the factory, and each length-specific OEM reference is reviewed under its own product configuration.

Frequently Asked Questions

Is this an original NVIDIA/Mellanox cable?

No. It is an HT-manufactured compatible cable for equipment that specifies OSFP-400G-4QAO, not an original NVIDIA/Mellanox-branded product.

Which lengths are covered by this product page?

This series page covers 30m (98ft). These are the length configurations identified from the source product records; contact us if a different project length is required.

Can this AOC cable connect different port speeds or breakout configurations?

Only when both host ports support the exact aggregate rate, lane mapping and breakout mode stated in the specifications. Confirm the equipment models before connecting unlike interface versions.

Does the cable need separate modules at each end?

No. The connector ends and cable form one complete direct-attach assembly. Do not attempt to detach the ends or treat the assembly as two independent modules.

Quality Assurance and Packaging

Every AOC assembly undergoes continuity and link testing, compatibility verification and a visual inspection of both connector ends. Cables are coiled without exceeding their minimum bend radius, fitted with connector protection and packed in anti-static bags or protective trays before cartoning. Project labels and packing lists are available for volume orders.

Shipping and Lead Time

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
