The MFA7U10-H010 compatible AOC cable provides 400G connectivity for NVIDIA/Mellanox equipment over a fixed 10m (33ft) assembly. Both ends use the stated OSFP to 2× QSFP56 arrangement. It is inspected and functionally checked before packing, with handling guidance designed to protect the connectors during installation and later service.

Signal and Lane Configuration
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.
Breakout Port Mapping
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.
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
The installation review for a 10m (33ft) link should include pathway length, support points, connector access and future maintenance. Route the integrated optical cable and both optical engines before attaching both ends, and avoid dragging it across connector panels. A final inspection should confirm that no latch, boot or jacket section carries unnecessary strain. Within this family, MFA7U10-H005 is shorter at 5m (16ft), while MFA7U10-H015 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 occupies the middle of this family between MFA7U10-H005 at 5m (16ft) and MFA7U10-H015 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.
Field Installation and Maintenance
Inspect the route and both connectors before installation, then support the cable without pulling on either connector housing. During maintenance, release the latch properly rather than using the cable as a handle. Keep protection on unused ends, and if the assembly is removed for later use, coil it loosely and record its part number so the same length can be returned to service. For this assembly, the listed conductor specification is 30AWG; 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 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.
Network and Protocol Considerations
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.
Quality Assurance and Packaging
The cable and both connectors are inspected before a functional link test. Connector protection and bend-safe packing reduce handling damage during transport and storage. Customer or site labels can be added for field inventories, with different lengths separated to simplify issue and return of spare assemblies. Volume orders can include customer references on the labels and carton list.
NVIDIA/Mellanox Compatibility and Factory Testing
A field-ready cable needs both correct identification and a stable operating link. Our pre-packing check therefore includes the connectors, host recognition and link behavior. For equipment with uncertain revision history, providing the host model and software release helps identify compatibility requirements before the assembly reaches the installation site. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
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.
What details assist a compatibility review?
Provide the equipment manufacturer, model, port type, hardware revision and software release, together with the OEM reference, required length and quantity.
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.
Ordering Information
Request the cable by its exact part number and length, and state the equipment model if compatibility confirmation is needed. Site orders can list quantities by rack or installation team. Any requested label should retain the part number so a removed or spare cable can still be identified accurately. Keep MFA7U10-H010 associated with 10m (33ft) throughout the order and receiving record.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. 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.
