NVIDIA/Mellanox MFA1A00-C0005 Compatible 100G QSFP28 4 x 25G NRZ Ethernet Active Optical Cable, 0.5m (2ft)

With a fixed 0.5m (2ft) cable and QSFP28 to QSFP28, the MFA1A00-C0005 compatible assembly simplifies 100G deployment. It is manufactured and tested by HT for NVIDIA/Mellanox equipment.

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.

MFA1A00-C0005 is the shortest of 11 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 MFA1A00-C001 at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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 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 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing MFA1A00-C0005; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

The HT cable carries the compatibility configuration associated with MFA1A00-C0005, while its mechanical assembly remains the fixed 0.5m (2ft) 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.

Use part number MFA1A00-C0005 for the 0.5m (2ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

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.

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.
