NVIDIA/Mellanox MFA1W00-W025 Compatible 400G QSFP-DD 8 x 50G PAM4 Ethernet Active Optical Cable, 25m (82ft)

This HT cable matches the MFA1W00-W025 requirement for NVIDIA/Mellanox equipment. The 25m (82ft) 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.

OEM Part Number: MFA1W00-W025HT Part Number: MFA1W00-W025

• Maximum power consumption: 8W Per End
• Minimum bend radius: 30mm
• Operating temperature: 0 to 70°C (32 to 158°F)

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.

The extended 25m (82ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

MFA1W00-W025 occupies the middle of this family between MFA1W00-W020 at 20m (66ft) and MFA1W00-W030 at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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 MFA1W00-W025 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.

This product is ordered as MFA1W00-W025 in 25m (82ft). 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.

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-W025 and the 25m (82ft) 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.
