MFA1A00-E010NVIDIA/Mellanox MFA1A00-E010 Compatible 100G QSFP28 4 x 25G NRZ Infiniband EDR Active Optical Cable, 10m (33ft)
For densely populated equipment, the fixed 10m (33ft) version of NVIDIA/Mellanox MFA1A00-E010 offers a clearly defined 100G link without separate optical modules or patch cords. The AOC assembly uses QSFP28 to QSFP28; its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

Signal and Lane Configuration
The listed modulation format is NRZ. 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.
High-Density Rack Integration
In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the minimum bend radius is 30mm; the stated power consumption is <2.2W; the jacket material is OFNP.
Power and Thermal Planning
The rated power consumption is <2.2W. 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.
Network and Protocol Considerations
The intended application is InfiniBand EDR. Listed interface and protocol references include IEEE 802.3 bm, SFF-8665. Confirm that the host firmware and port configuration support the same operating mode.
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
Extended reach changes the installation checks for MFA1A00-E010. Confirm that 10m (33ft) follows the intended route without tension, then verify that intermediate supports do not squeeze the jacket or hide the connectors behind adjacent cables. Both hosts must still match the stated interface and lane configuration. Within this family, MFA1A00-E007 is shorter at 7m (23ft), while MFA1A00-E015 is the next longer choice at 15m (49ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
MFA1A00-E010 occupies the middle of this family between MFA1A00-E007 at 7m (23ft) and MFA1A00-E015 at 15m (49ft). It adds 3m 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.
Quality Assurance and Packaging
Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Volume orders can include customer references on the labels and carton list.
Ordering Information
Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. Quantity and any labeling instructions should be attached specifically to MFA1A00-E010.
NVIDIA/Mellanox Compatibility and Factory Testing
The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MFA1A00-E010.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
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.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production quantities confirmed at order stage. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.
