NVIDIA/Mellanox MFA1A00-E050 Compatible 100G QSFP28 4 x 25G NRZ Infiniband EDR Active Optical Cable, 50m (164ft)

This HT cable matches the MFA1A00-E050 requirement for NVIDIA/Mellanox equipment. The 50m (164ft) 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.

OEM Part Number: MFA1A00-E050HT Part Number: MFA1A00-E050

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MFA1A00-E050
• 100G connectivity at 100Gbps
• Interface configuration: QSFP28 to QSFP28
• Fixed length and part number: 50m (164ft), MFA1A00-E050
• 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 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 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.

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 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.

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 50m (164ft) 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-E050 occupies the middle of this family between MFA1A00-E030 at 30m (98ft) and MFA1A00-E100 at 100m (328ft). It adds 20m over the shorter option for extra routing clearance, while the next longer version adds another 50m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The assembly is configured for equipment that recognizes MFA1A00-E050. 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.

When ordering, specify MFA1A00-E050, cable length 50m (164ft) 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.

Every MFA1A00-E050 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 50m (164ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

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.
