NVIDIA/Mellanox MFA1A00-C003 Compatible 100G QSFP28 4 x 25G NRZ Ethernet Active Optical Cable, 3m (10ft)

This HT cable matches the MFA1A00-C003 requirement for NVIDIA/Mellanox equipment. The 3m (10ft) 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-C003HT Part Number: MFA1A00-C003

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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

MFA1A00-C003 occupies the middle of this family between MFA1A00-C002 at 2m (7ft) and MFA1A00-C005 at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 2m. 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. 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.

For this NVIDIA/Mellanox application, testing combines digital identification with actual traffic-link verification and optical link operation, receive activity and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

Use part number MFA1A00-C003 for the 3m (10ft) 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.

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, MFA1A00-C003 and the 3m (10ft) length for easier inventory control.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
