NVIDIA/Mellanox MFA7A20-C030 Compatible 100G QSFP28 4 x 25G NRZ to 2 x 50G QSFP28 2 x 25G NRZ Ethernet Active Optical Breakout Cable, 30m (98ft)

This HT cable matches the MFA7A20-C030 requirement for NVIDIA/Mellanox equipment. The 30m (98ft) assembly supports 100G operation and provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly; its complete electrical and mechanical details are listed below.

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 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 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 30m (98ft) 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.

MFA7A20-C030 occupies the middle of this family between MFA7A20-C020 at 20m (66ft) and MFA7A20-C050 at 50m (164ft). It adds 10m over the shorter option for extra routing clearance, while the next longer version adds another 20m. 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 (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.

Our compatibility setup for NVIDIA/Mellanox MFA7A20-C030 is checked together with the physical 30m (98ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and optical link operation, receive activity and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

When ordering, specify MFA7A20-C030, cable length 30m (98ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

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.
