NVIDIA/Mellanox MFA1W00-W001 Compatible 400G QSFP-DD 8 x 50G PAM4 Ethernet Active Optical Cable, 1m (3ft)

This HT cable matches the MFA1W00-W001 requirement for NVIDIA/Mellanox equipment. The 1m (3ft) assembly supports 400G operation and provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly; its complete electrical and mechanical details are listed below.

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 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.

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), MFA1W00-W001 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.

MFA1W00-W001 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 MFA1W00-W002 at 2m (7ft), adding 1m 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.

Each MFA1W00-W001 compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe optical link operation, receive activity and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended NVIDIA/Mellanox platform should be included with the order.

Use part number MFA1W00-W001 for the 1m (3ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, MFA1W00-W001 and the 1m (3ft) length for easier inventory control.

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.
