NVIDIA/Mellanox MFA1W00-W007 Compatible 400G QSFP-DD 8 x 50G PAM4 Ethernet Active Optical Cable, 7m (23ft)

For short, high-density connections, this AOC cable combines 400G performance with a fixed 7m (23ft) cable run. It corresponds to NVIDIA/Mellanox MFA1W00-W007 and uses a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

OEM Part Number: MFA1W00-W007HT Part Number: MFA1W00-W007

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MFA1W00-W007
• 400G connectivity at 400Gbps
• Interface configuration: QSFP-DD to QSFP-DD
• Fixed length and part number: 7m (23ft), MFA1W00-W007
• Cable construction: OM4
• 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.

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.

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 7m (23ft) 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-W007 occupies the middle of this family between MFA1W00-W005 at 5m (16ft) and MFA1W00-W010 at 10m (33ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 3m. 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.

The HT cable carries the compatibility configuration associated with MFA1W00-W007, while its mechanical assembly remains the fixed 7m (23ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new NVIDIA/Mellanox software can request a pre-order check.

Quote HT part number MFA1W00-W007 with the required quantity. The 7m (23ft) 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.

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-W007 and the 7m (23ft) length for easier inventory control.

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.
