NVIDIA/Mellanox MFA7A20-C001 Compatible 100G QSFP28 4 x 25G NRZ to 2 x 50G QSFP28 2 x 25G NRZ Ethernet Active Optical Breakout Cable, 1m (3ft)

For short, high-density connections, this AOC cable combines 100G performance with a fixed 1m (3ft) cable run. It corresponds to NVIDIA/Mellanox MFA7A20-C001 and uses a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

The listed modulation format is 4x 25G-NRZ to 2x 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.

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.

At 1m (3ft), MFA7A20-C001 is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

MFA7A20-C001 is the shortest of 10 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is MFA7A20-C003 at 3m (10ft), adding 2m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The rated power consumption is 2.2W (100G Per End)1.5W (50G 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.

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 determined by the host interface and protocol support. Listed interface and protocol references include QSFP28 Electrical MSA, SFF-8636, SFF-8665. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP28 to 2x QSFP28 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.

The assembly is configured for equipment that recognizes MFA7A20-C001. Before shipment, we inspect both connectors and verify identification, link establishment and optical link operation, receive activity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Quote HT part number MFA7A20-C001 with the required quantity. The 1m (3ft) 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, MFA7A20-C001 and the 1m (3ft) length for easier inventory control.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
