Key Features of NVIDIA/Mellanox MMA4Z00-NS400 Compatible LINK-PP 400G OSFP
NVIDIA/Mellanox MMA4Z00-NS400 Compatible LINK-PP features 400Gbps InfiniBand NDR transmission, low energy draw, and multi-mode optical connectivity up to 50m. It unifies 850nm array technology, a secure MPO-12/APC interface, and comprehensive digital diagnostics to streamline network management.
This transceiver module fully complies with the OSFP MSA specification to guarantee physical and electrical compatibility with industry switches. Operating within commercial temperature ranges, the unit draws a maximum power consumption of only 8.5W to reduce thermal load across dense rack layouts.
MMA4Z00-NS400: 400 Gbps Connectivity for InfiniBand NDR Clusters
Massive 400Gbps aggregate throughput is achieved across 4 parallel channels using advanced 100G PAM4 signaling. These fast transmission speeds make the hardware an ideal choice for latency-critical AI computing nodes and large InfiniBand NDR compute clusters.
MMA4Z00-NS400 Module with 850nm Wavelength
An array of 850nm VCSEL transmitters handles optical signal generation across parallel fiber strands. This specific near-infrared spectrum provides an efficient optical source tailored for short-distance multi-mode connectivity inside server rooms.
MMA4Z00-NS400 Module Supporting 50m Transmission
Optical reach extends up to 50m when using standard OM4 multi-mode fiber cabling. Such a link span easily covers intra-rack connections, top-of-rack patching, and neighboring row switches without needing single-mode infrastructure.
MMA4Z00-NS400 Module with MPO-12/APC Interface
Equipped with an MPO-12/APC optical interface, the module establishes firm, repeatable connections with OM4 trunk cables. The precision design significantly suppresses internal reflections to optimize optical return loss across the entire transceiver link.
MMA4Z00-NS400 Module with DDM for Real-Time Monitoring
Integrated digital diagnostic monitoring circuits report real-time telemetry over the two-wire management interface. Network administrators can instantly check operating temperature, supply voltage, laser bias current, and optical Rx/Tx power to prevent link downtime.

A:
Yes, up to 50 m on OM4 is supported, but only with an OM4 fiber assembly terminated with MPO-12 APC connectors and with total channel insertion loss within the module specification. The exact link budget cannot be derived from the feature list alone; it depends on the module’s Tx OMA, Rx sensitivity, connector/splice count, and aging margin. In practice, reserve margin and verify the link meets the required pre-FEC BER / FEC threshold, e.g., KP4 FEC for 400G Ethernet. By
admin
A:
No. This module uses an MPO-12 APC optical interface. You must use MPO-12 APC cable assemblies, either patch cords or trunks. Do not mate UPC and APC connectors, because the endface geometry is different; this can cause high insertion loss, poor return loss, and possible endface damage. Also confirm gender, polarity, and key orientation. By
admin
A:
Yes, provided your switch port is configured for 400G Ethernet and supports the relevant 400G Ethernet mode, OSFP form factor, CMIS management, PAM4 106.25Gbps per lane, and required FEC. The transceiver itself is not “configured” to Ethernet; the switch port profile determines whether it runs 400G Ethernet or InfiniBand NDR. Vendor firmware and module coding should also be confirmed.

We integrated these transceivers into our enterprise low-latency core switching matrix. The OSFP housing fits snugly without thermal throttling during peak load stress tests, staying around 42°C. Full compliance with IEEE 802.3 and InfiniBand NDR protocols makes high-density server rack deployment totally painless. =)

Outstanding optical transceiver for high-throughput AI GPU fabric interconnects. We benchmarked 16 of these OSFP optical transceivers across adjacent compute racks using MPO-12/APC patch cords at 40m. Inbuilt FEC kept correctable errors near baseline with zero uncorrectable frames, and DDM live stats tracked clean power levels across all 850nm VCSEL channels. :-D

The LO-M85400-SR4C transceivers run fast and rock solid at 400G NDR speed, but the outer packaging box was slightly dented during international freight delivery. Optics inside were completely unharmed.
