NVIDIA/Mellanox MFA7U10-H020 Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 2 x 200G QSFP56 4 x 50G PAM4 InfiniBand HDR Active Optical Breakout Cable, 20m (66ft)

The MFA7U10-H020 cable offers a direct OSFP to 2× QSFP56 connection at 400Gbps. Its 20m (66ft) length and AOC construction are intended for NVIDIA/Mellanox equipment, with no separate transceiver-and-patch-cord assembly required.

The listed modulation format is OSFP-8x 50G-PAM4QSFP56-4x 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.

The extended 20m (66ft) 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.

MFA7U10-H020 occupies the middle of this family between MFA7U10-H015 at 15m (49ft) and MFA7U10-H030 at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 10m. 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 30AWG conductors, 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 determined by the host interface and protocol support. Listed interface and protocol references include OSFP Rev. 5.0, SFF-8679, SFF-8661, SFF-8636, CMIS Rev 4.0, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP to 2× 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.

Our compatibility setup for NVIDIA/Mellanox MFA7U10-H020 is checked together with the physical 20m (66ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and optical link operation, receive activity and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

When ordering, specify MFA7U10-H020, cable length 20m (66ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Every MFA7U10-H020 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 20m (66ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

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.
