Dell AOC-Q56DD-400G-1M Compatible 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable, 1m (3ft)

Dell AOC-Q56DD-400G-1M Compatible 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable, 1m (3ft)

The HT-manufactured AOC-Q56DD-400G-1M compatible cable provides 400G connectivity for Dell equipment. This 1m (3ft) version is a factory-terminated active optical link with the optical engines and fiber integrated into the assembly, with an exact part number and length that can be matched directly to the equipment requirement.

Signal and Lane Configuration

The listed modulation format is PAM4. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

Position Within the Length Range

AOC-Q56DD-400G-1M is the shortest of 13 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is AOC-Q56DD-400G-2M at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Power and Thermal Planning

The rated power consumption is 8W Per End. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

Cable Construction and Routing

This assembly uses OFNP jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

Network and Protocol Considerations

The intended application is 8x 50G-PAM4. Listed interface and protocol references include IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA,QSFP-DD-CMIS-rev4p0. Confirm that the host firmware and port configuration support the same operating mode.

Integrated Optical Assembly

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

Length Selection and Installation Planning

At 1m (3ft), AOC-Q56DD-400G-1M is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

Dell Compatibility and Factory Testing

Compatibility is more than matching the QSFP-DD to QSFP-DD shape. This assembly is prepared for hosts expecting AOC-Q56DD-400G-1M and is checked for identification, stable link behavior and optical link operation, receive activity and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Ordering Information

This product is ordered as AOC-Q56DD-400G-1M in 1m (3ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Frequently Asked Questions

Is this an original Dell cable?

No. It is an HT-manufactured compatible alternative for equipment that specifies Dell AOC-Q56DD-400G-1M.

Can I use it between different speeds or interface types?

Only when both hosts explicitly support the same data rate, lane mapping and breakout configuration. Mechanical fit alone is not proof of interoperability.

What information should I provide for a compatibility check?

Provide the host manufacturer, equipment model, port type, hardware revision and software release, together with the OEM part number and required quantity.

Does this page include more than one cable length?

No. This page is dedicated to 1m (3ft) and part number AOC-Q56DD-400G-1M. Other lengths have their own part numbers and product pages.

Quality Assurance and Packaging

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
