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

The HT-manufactured AOC-D-D-400G-1M compatible cable provides 400G connectivity for Arista Networks 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.

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.

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.

At 1m (3ft), AOC-D-D-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.

AOC-D-D-400G-1M is the shortest of 9 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-D-D-400G-3M at 3m (10ft), adding 2m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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.

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.

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.

Compatibility is more than matching the QSFP-DD to QSFP-DD shape. This assembly is prepared for hosts expecting AOC-D-D-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.

Quote HT part number AOC-D-D-400G-1M with the required quantity. The 1m (3ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
