NVIDIA/Mellanox QSFP-400G-AO Compatible 400G QSFP112 4 x 100G PAM4 Ethernet Active Optical Cable

NVIDIA/Mellanox QSFP-400G-AO Compatible 400G QSFP112 4 x 100G PAM4 Ethernet Active Optical Cable

The QSFP-400G-AO compatible series is designed for NVIDIA/Mellanox hosts requiring a 400G AOC connection. Its QSFP112 to QSFP112 arrangement is supplied as a complete optical assembly with permanently attached ends and integrated fiber. Use the specifications to assess the physical assembly, then follow the exact length and part-number links when preparing a bill of materials or requesting a compatibility check.

Applications and Deployment

An AOC removes the separate module-and-fiber interfaces from a high-speed connection. Both optical ends remain attached to the cable, simplifying polarity control and connector handling. Host identification, wavelength plan, aggregate rate and any breakout configuration must still agree across the link. For this series, the listed interface is QSFP112 to QSFP112 and the aggregate rate is 400G.

Cable Construction and Routing

The specification table records the jacket material is OFNP; the minimum bend radius is 30mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is 10W Per End. Use those values when preparing the rack pathway and receiving checklist. Do not pull a connector by its cable, compress the run under tight ties or force excess length into a sharp coil. Connector protection should remain in place until the assembly is ready for insertion.

Mixed-Vendor Network Operation

A mixed-vendor link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether the two ends use the same compatibility requirement. The related brand links below help locate equivalent-length assemblies, while the physical form factor and lane arrangement must still agree across the complete path. For this series, keep the interface rate, AOC construction and length-specific OEM reference together throughout that review.

NVIDIA/Mellanox Compatibility and Factory Testing

Testing addresses the brand-specific identification as well as the operating link and available diagnostics. The same physical cable family can require a different host identity for another equipment vendor, so the intended platform should be supplied when a deployment combines multiple brands or unusual hardware revisions. Series-level inspection is followed by the exact length and OEM configuration selected for dispatch. Functional verification includes link establishment and diagnostic indications where the host exposes them.

Ordering Information

For mixed-vendor projects, identify the equipment at both ends along with the OEM reference, length and quantity. Order each compatibility version under its own part number. If spare assemblies are required, list them separately so labels and test records remain unambiguous. For this series, follow the corresponding length link, quote that exact OEM part number and keep different lengths on separate order lines. HT part number QSFP-400G-AO identifies the product family; the linked page provides the final length-specific identity.

Quality Assurance and Packaging

Both ends are inspected and the complete assembly is powered up for a functional check before packing. Connectors are protected individually and the cable is secured without tight bends. Optional labels can distinguish host brand, OEM reference and length for easier spares management. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.

Frequently Asked Questions

Is this an original NVIDIA/Mellanox cable?

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

Are different lengths and OEM part numbers separate products?

Yes. Where a length has its own OEM reference, follow the corresponding link above and order that exact part number on its own line. Do not substitute another length only because the connector arrangement is the same.

Does this AOC cable require separate modules at each end?

No. The connector ends and cable form one complete direct-attach assembly. The ends are not detachable standalone transceivers, and the complete product is tested together.

What information helps confirm compatibility?

Provide the equipment manufacturer and model, port type, hardware revision and software release, together with the required OEM reference, length and quantity. Breakout projects should also identify the intended lane configuration.
