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

Use the MFA7U10-H020-FLT compatible assembly where a 400G connection is required between compatible ports. This page covers the 20m (66ft) version only, with its own HT part number, specifications and compatibility verification.

The listed modulation format is 8x 50G-PAM4 to Dual 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 OSFP (RHS/Flat Top) to 2x 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 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-FLT occupies the middle of this family between MFA7U10-H015-FLT at 15m (49ft) and MFA7U10-H030-FLT 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 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 CMIS 4.0, SFF-8636，IEEE 802.3 bs-2*200GAUI-4, IEEE 802.3 bs-200GAUI-4, OSFP MSA, SFF-8679, SFF-8661. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with MFA7U10-H020-FLT, while its mechanical assembly remains the fixed 20m (66ft) 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 MFA7U10-H020-FLT for the 20m (66ft) 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.

Every MFA7U10-H020-FLT 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.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
