NVIDIA/Mellanox MFA1A00-C020 Compatible 100G QSFP28 4 x 25G NRZ Ethernet Active Optical Cable, 20m (66ft)

The HT-manufactured MFA1A00-C020 compatible cable provides 100G connectivity for NVIDIA/Mellanox equipment. This 20m (66ft) 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.

OEM Part Number: MFA1A00-C020HT Part Number: MFA1A00-C020

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MFA1A00-C020
• 100G connectivity at 100Gbps
• Interface configuration: QSFP28 to QSFP28
• Fixed length and part number: 20m (66ft), MFA1A00-C020
• Cable construction: Optical Cable
• Maximum power consumption: <2.2W
• Minimum bend radius: 30mm
• Operating temperature: 0 to 70°C (32 to 158°F)

The listed modulation format is 4x 25G-NRZ to 4x 25G-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.

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 100G Ethernet. 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.

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.

The extended 20m (66ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

MFA1A00-C020 occupies the middle of this family between MFA1A00-C015 at 15m (49ft) and MFA1A00-C025 at 25m (82ft). 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.

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.

The HT cable carries the compatibility configuration associated with MFA1A00-C020, while its mechanical assembly remains the fixed 20m (66ft) 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.

Quote HT part number MFA1A00-C020 with the required quantity. The 20m (66ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, MFA1A00-C020 and the 20m (66ft) length for easier inventory control.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
