NVIDIA/Mellanox MFA7A50-C007 Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Ethernet Active Optical Breakout Cable, 7m (23ft)

Designed for hosts that recognize MFA7A50-C007, this QSFP28 to 4x SFP28 cable delivers 100G transmission over a fixed 7m (23ft) assembly. Its AOC construction provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

The listed modulation format is QSFP28-4x 25G-NRZ SFP28-1x 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 QSFP28 to 4x SFP28 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 7m (23ft) 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.

MFA7A50-C007 occupies the middle of this family between MFA7A50-C005 at 5m (16ft) and MFA7A50-C010 at 10m (33ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 3m. 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 (QSFP28 End)0.8W (SFP28 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 MSA, SFP28 MSA. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with MFA7A50-C007, while its mechanical assembly remains the fixed 7m (23ft) 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 MFA7A50-C007 with the required quantity. The 7m (23ft) 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.

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.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
