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.
Position Within the Length Range
MFA7U10-H030 is the longest of 5 verified length options in this family. Compared with MFA7U10-H020 at 20m (66ft), it provides 10m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.
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 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.
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 30m (98ft) reach of MFA7U10-H030 is useful only when the managed pathway requires it; straight-line distance between ports is not a sufficient measurement. Check the route around rack rails, cable managers and maintenance clearances, then protect the integrated optical cable and both optical engines from tight bends and unsupported spans. The next shorter verified assembly is MFA7U10-H020 at 20m (66ft), which is the better comparison when the managed route leaves substantial unused cable.
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. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
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. Quantity and any labeling instructions should be attached specifically to MFA7U10-H030.
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. Neutral packaging and customer-specific packing documentation are available on request.
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-H030.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
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.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
