ADVANCED FEATURES:

Automatic Protocol Switching:

The MMA4Z00‑NS400 can intelligently detect whether it is connected to an InfiniBand NDR or Ethernet network. This allows the transceiver to automatically configure itself for the appropriate protocol, eliminating manual intervention. The feature ensures seamless interoperability in mixed-protocol environments, reducing downtime and simplifying deployment in large-scale HPC and AI infrastructures.

Power Optimization & Dynamic Mode:

The transceiver supports flexible power modes. In full 400G operation, all four PAM4 lanes are active for maximum throughput, consuming approximately 8.5 W. When paired with a 1:2 splitter cable, it can operate in 200G mode using only two lanes, reducing power consumption to around 5.5 W. This dynamic power management helps lower operational costs and reduces heat generation in high-density racks.

Integrated Diagnostics (CMIS 4.0):

Equipped with Common Management Interface Specification (CMIS) 4.0, the MMA4Z00‑NS400 provides continuous real-time monitoring of critical parameters such as optical power, temperature, supply voltage, and transceiver health. Administrators can proactively detect potential faults, schedule preventive maintenance, and ensure reliable, uninterrupted operation across large-scale deployments.

Thermal & Mechanical Optimization:

The flat-top OSFP form factor is specifically designed for efficient heat dissipation. It aligns perfectly with host cooling fins or other chassis airflow designs, maintaining optimal operating temperatures even under heavy workloads. This thermal optimization ensures long-term reliability and stable performance in dense server and switch racks.

Hot-Pluggable & Safe Design:

Fully hot-swappable, Class 1 laser-compliant, and RoHS-certified, the MMA4Z00‑NS400 can be installed or replaced without powering down equipment. This feature minimizes operational disruption during maintenance or upgrades, which is critical in high-performance data centers, HPC clusters, and AI compute environments.

High-Density, Scalable Deployment:

Its compact OSFP module design allows multiple transceivers to be installed in a single chassis, enabling high port density and scalable network expansion. This is ideal for AI workloads, cloud data centers, and HPC clusters where space efficiency and scalability are crucial.

Versatile Short-Reach Connectivity:

Designed for multimode fiber networks, it supports distances up to 50 m on OM4 and 30 m on OM3. This makes it suitable for intra-rack and inter-rack connections, providing high-bandwidth, low-latency links for compute clusters, storage arrays, and network switches.

Optimized for NVIDIA Platforms:

Fully certified and optimized for Quantum-2 switches, DGX-H100 systems, ConnectX‑7 NICs, and BlueField‑3 DPUs, ensuring maximum compatibility and performance across NVIDIA’s networking and AI compute ecosystem. This guarantees that all features, including telemetry and diagnostics, are fully supported in NVIDIA-powered infrastructures.

Enhanced Reliability & Performance:

The transceiver’s advanced design ensures consistent signal integrity, low latency, and high data throughput. Coupled with its thermal efficiency and power optimization, it delivers reliable operation even in demanding HPC, AI, and cloud workloads.

Future-Ready & Flexible:

The OSFP form factor and modular PAM4 lanes make the transceiver future-proof, capable of adapting to evolving networking standards, higher bandwidth requirements, and next-generation HPC or AI infrastructures.
