NVIDIA/Mellanox MFA7U20-H015 Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 4 x 100G QSFP56 2 x 50G PAM4 InfiniBand HDR Active Optical Breakout Cable, 15m (49ft)

This 15m (49ft) AOC cable is built for NVIDIA/Mellanox equipment requiring the MFA7U20-H015 interface. The 400Gbps link uses OSFP (IHS/Finned Top) to 4x QSFP56 and is supplied as one complete tested assembly.

The listed modulation format is OSFP-8x 50G-PAM4QSFP56-2x 50G-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.

MFA7U20-H015 occupies the middle of this family between MFA7U20-H010 at 10m (33ft) and MFA7U20-H020 at 20m (66ft). 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 10W (OSFP End) 5.5W (QSFP56 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 400G to 4x 100G. Listed interface and protocol references include IEEE 802.3cd, CMIS 5.0, SFF-8661, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 4x QSFP56 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

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 15m (49ft) 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.

The HT cable carries the compatibility configuration associated with MFA7U20-H015, while its mechanical assembly remains the fixed 15m (49ft) 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.

Use part number MFA7U20-H015 for the 15m (49ft) 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, MFA7U20-H015 and the 15m (49ft) 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.
