NVIDIA/Mellanox MFA7U10-H010-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, 10m (33ft)
For buyers working from an equipment parts list, MFA7U10-H010-FLT identifies more than a connector style. It refers here to a 10m (33ft) AOC cable for NVIDIA/Mellanox hosts, supporting 400G operation with OSFP (RHS/Flat Top) to 2x QSFP56. The sections below separate the OEM cross-reference, physical specification and HT factory checks for straightforward purchasing review.

Signal and Lane Configuration
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.
Network and Protocol Considerations
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.
Breakout Port Mapping
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.
Integrated Optical Assembly
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.
Length Selection and Installation Planning
Measure twice before deploying this 10m (33ft) cable: once along the planned route and again after accounting for service access. The objective is adequate reach without a concealed surplus. Support the integrated optical cable and both optical engines, preserve front-panel clearance and check that nearby power cords or sharp hardware cannot damage the jacket. Within this family, MFA7U10-H005-FLT is shorter at 5m (16ft), while MFA7U10-H015-FLT is the next longer choice at 15m (49ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
MFA7U10-H010-FLT occupies the middle of this family between MFA7U10-H005-FLT at 5m (16ft) and MFA7U10-H015-FLT at 15m (49ft). 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.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 10W (OSFP End) 5.5W (QSFP56 Per End); the jacket material is OFNP.
Power and Thermal Planning
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.
Cable Construction and Routing
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.
NVIDIA/Mellanox Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. The check includes receive activity and diagnostic indications, followed by a final inspection of both ends.
Ordering Information
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. This page’s fixed configuration is 10m (33ft); another length must be quoted under its corresponding part number.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. Standard protective packing is used by default, with project documentation arranged when requested.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MFA7U10-H010-FLT.
How should an unused assembly be stored?
Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.
Can different brands be connected with the same assembly?
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
Does this order code cover multiple lengths?
No. MFA7U10-H010-FLT refers here to 10m (33ft). Every other verified length has a separate part number and page in the length list.
Shipping and Lead Time
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
