Mellanox MMA4Z00-NS400 400Gb/s OSFP SR4 Transceiver
Upgrade your data center’s backbone with the Mellanox MMA4Z00-NS400 400Gb/s OSFP SR4 transceiver. This high-performance, single-port OSFP module is purpose-built for ultra-fast, dependable intra- and inter-rack connectivity in modern hyperscale environments. Delivering a full 400 Gb/s of aggregate throughput across four parallel 100 Gb/s lanes, this transceiver enables low-latency, high-density networking that scales with growing workloads—from cloud computing and AI inference to large-scale storage and virtualization. The MMA4Z00-NS400 is designed to meet the demanding requirements of 400G networking, offering robust compatibility with standard 400GBASE-SR4 specifications and seamless integration into OSFP-enabled switch and server platforms. Its multimode SR4 50 m reach makes it ideal for short-reach deployments inside data centers, where high-bandwidth connections between servers, switches, and storage arrays are essential for accelerating performance and reducing bottlenecks.
- Ultra-high throughput: Delivers 400 Gb/s of aggregated data transfer in a single OSFP module by combining four 100 Gb/s lanes, enabling scalable uplinks, server-to-server interconnects, and rapid data movement across racks.
- OSFP form factor for high-density deployments: The OSFP (OFP) package supports dense packing in modern switch and server bays, enabling easier hot-swapping and streamlined cabling in tight data-center spaces.
- Multimode SR4 reach of 50 meters on OM4 fiber: Optimized for short-reach interconnects within data centers, providing reliable 400G links over standard multimode fiber with excellent channel count and spectral efficiency.
- 850 nm VCSEL-based SR4 technology: Utilizes well-established multimode SR4 optics for robust performance across typical data-center fiber plant, with low insertion loss and stable operation under varying thermal conditions.
- Interoperable, standards-forward design: Built to support industry-standard 400GBASE-SR4 specifications and compatible with a broad ecosystem of 400G ethernet fabrics, switches, and storage arrays that accept OSFP modules.

How to install Mellanox MMA4Z00-NS400
Install the Mellanox MMA4Z00-NS400 like other OSFP 400G transceivers to ensure optimal performance and reliability. Follow these general steps to achieve a successful deployment:
- Power down or enable hot-swap per your hardware vendor’s guidelines, ensuring you follow proper ESD precautions before handling the module.
- Insert the MMA4Z00-NS400 module firmly into an available OSFP port on a compatible switch, router, or server motherboard that supports 400G OSFP transceivers.
- Connect the fiber harness using an MPO/MTP fiber cable configured for SR4 lanes, ensuring the correct polarity and alignment for all four lanes.
- Power up the device and verify the link status and lane status indicators on the host switch or NIC. Confirm that all four 100G lanes are active and negotiating properly.
- Run a basic baseline test (loopback or cross-connect test) and verify performance, error-free data transmission, and inter-operability with the surrounding network fabric. Update firmware or driver software if required by your platform.
