The Mellanox MMA1Z00-NS400 Compatible TAA 400GBase-SR4 QSFP112 Transceiver is engineered to deliver robust, 400 Gigabit-per-second links over multimode fiber (MMF), enabling dense, low-latency interconnects for modern cloud and hyperscale networks. This TAA-compliant module is designed to work seamlessly within Mellanox ecosystems and CMIS 5.0–compliant environments, offering dependable interoperability with a broad range of switches and optical infrastructure. With digital optical monitoring (DOM) for real-time health checks, high optical power stability, and a plug-and-play form factor, this transceiver simplifies deployment and reduces operational risk in demanding data-center deployments. Whether you’re upgrading an existing fabric or deploying a new 400G fabric, this MMF-based transceiver optimizes bandwidth utilization while keeping management straightforward and costs predictable.

• The 400GBase-SR4 QSFP112 form factor supports multi-lane MMF deployments, delivering dense, high-speed links over MPO/MTP connectors with a reach suitable for short-reach data-center corridors and rack-to-rack interconnects. The MMF 850 nm design balances performance and compatibility with common data-center fiber infrastructure, enabling reliable transmission across fiber channels with low modal dispersion. This module is purpose-built for environments where high traffic, low latency, and compact port counts are essential to scale your network.
• Designed for maximum throughput, this transceiver uses an MMF-optimized 850 nm VCSEL configuration that achieves high optical efficiency and consistent link budgets across standardized 50-meter links. The technology behind the 400GBase-SR4 interface takes advantage of parallel lanes to deliver aggregated bandwidth while maintaining signal integrity, eye safety, and robust performance under varying temperature and load conditions.
• Digital Optical Monitoring (DOM) provides continuous insight into link status, laser temperature, laser current, voltage, and optical power. This range of diagnostics enables proactive maintenance, rapid fault isolation, and streamlined serviceability. IT teams can leverage DOM data to optimize power budgets, monitor aging components, and verify performance during installation, upgrade, or recovery operations.
• CMIS 5.0 compliance ensures interoperability across CMIS-aware devices and management platforms, simplifying device discovery, inventory, and lifecycle management. This compatibility reduces vendor lock-in and makes it easier to integrate the transceiver into mixed-brand data centers or standardized CMIS-managed networks. The module’s CMIS alignment also helps ensure firmware updates and policy enforcement remain consistent across devices from different vendors.
• Targeted for Mellanox deployments, this transceiver offers reliable pin-to-pin compatibility, robust mechanical fit, and predictable performance within Mellanox-based or CMIS-compatible infrastructures. Its TAA (Trade Agreements Act) compliance supports procurement in government and regulated enterprise environments, ensuring procurement flexibilities without compromising performance or reliability.

how to install Mellanox MMA1Z00-NS400

• Power down the host system and any devices connected to the network port where the transceiver will be installed. Follow standard ESD precautions to protect the module and the equipment from static discharge.
• Handle the transceiver by its edges and align the QSFP112 module with the appropriate switch or director’s QSFP/SFP+ slot. Ensure the slot orientation matches the device’s physical port layout to avoid bending or forcing the connector.
• Gently insert the module into the slot until the latch engages and seats firmly. Do not apply excessive force; if the module does not click into place, remove it, recheck alignment, and reinsert.
• Attach the MMF cable with MPO/MTP connectors to the transceiver, ensuring the fiber ferrules are clean and free of dust. Maintain proper fiber polarity and avoid bending radii that exceed recommended limits. Remove dust caps only after the connector is ready to mate with the port.
• Power on the device and verify link status. Use the DOM readings to confirm optical power, temperature, and voltage are within expected ranges. If supported, run a CMIS-enabled management tool to verify device recognition, software version alignment, and port health metrics.
• Perform a basic throughput test to confirm that the 400GBase-SR4 link is operating at expected speeds. Review error counters and drift in DOM metrics to identify any need for re-termination, re-cabling, or firmware updates.

Frequently asked questions

• Q: What is 400GBase-SR4 and where is this transceiver used? A: 400GBase-SR4 is a high-density four-lane short-reach standard designed for multi-mode fiber. The Mellanox MMA1Z00-NS400 transceiver uses QSFP112 to deliver aggregated 400 Gbps over MMF up to 50 meters, ideal for data-center interconnects, top-of-rack, and aggregation layers where space and power are at a premium.
• Q: Is this module compatible with switches and optical components from vendors other than Mellanox? A: Yes, the module is CMIS 5.0 compliant, which enhances interoperability with CMIS-enabled devices and management platforms. However, actual compatibility with non-Mellanox devices can depend on vendor-specific firmware, port configurations, and supported optics standards. Always verify with your supplier and test in a controlled environment if you plan cross-vendor deployments.
• Q: What fiber type and distance are supported by this transceiver? A: The transceiver is designed for multimode fiber (MMF) with an 850 nm wavelength, supporting distances up to 50 meters. This makes it well-suited for short-reach data-center links and campus deployments that demand high throughput with a relatively compact footprint.
• Q: Does the transceiver provide DOM, and what details can be monitored? A: Yes, DOM is supported. Real-time monitoring includes optical power, laser temperature, laser current, and supply voltage. This information helps with proactive maintenance, link reliability, and rapid fault isolation during provisioning or troubleshooting.
