NVIDIA/Mellanox MFA7U10-H003-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, 3m (10ft)

The HT-manufactured MFA7U10-H003-FLT compatible cable provides 400G connectivity for NVIDIA/Mellanox equipment. This 3m (10ft) version is a factory-terminated active optical link with the optical engines and fiber integrated into the assembly, with an exact part number and length that can be matched directly to the equipment requirement.

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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

MFA7U10-H003-FLT is the shortest of 6 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is MFA7U10-H005-FLT at 5m (16ft), adding 2m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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-H003-FLT, while its mechanical assembly remains the fixed 3m (10ft) 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.

This product is ordered as MFA7U10-H003-FLT in 3m (10ft). 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.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

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.
