Mellanox MMA4Z00-NS Compatible TAA 800GBase-2xSR4 PAM4 OSFP Transceiver

Meet the Mellanox MMA4Z00-NS Compatible TAA 800GBase-2xSR4 PAM4 OSFP Transceiver, a cutting-edge solution engineered for blazing-fast data transmission in modern data centers. This OSFP transceiver leverages PAM4 signaling to deliver 800G of aggregate throughput over multimode fiber (MMF), optimizing rack density and lowering total cost of ownership. Built to be compatible with a wide range of vendor ecosystems, it offers dependable performance, streamlined procurement with CMIS 5.0, and real-time visibility through Digital Optical Monitoring (DOM). With a reach of up to 50 meters on MMF at 850 nm, this module is tailor-made for intra-data-center links, spine-leaf topologies, and dense aggregation layers where low latency and high bandwidth are non-negotiable.

• Ultra-high-density 800G connectivity: This transceiver uses 2x SR4 PAM4 lanes to deliver robust aggregate bandwidth in a compact OSFP footprint, enabling data centers to scale capacity without sacrificing port density. The PAM4 approach increases data throughput per lane while maintaining strong signal integrity, making it ideal for modern spine-and-leaf architectures and high-performance compute clusters.
• MMF 850 nm, 50 m reach: Optimized for multi-mode fiber networks, the 850 nm wavelength supports reliable short-reach links within data centers. With a 50-meter reach, it bridges core devices like switches and routers across racks or rows, delivering consistent performance in mid-range campus deployments and dense server environments.
• 2xMPO fiber connectors with DOM and CMIS 5.0: The dual MPO interface supports high-bandwidth fiber coupling while Digital Optical Monitoring provides real-time insight into optical power, temperature, and link status. CMIS 5.0 compliance ensures your procurement processes stay streamlined, enabling easier compatibility checks and supply chain management across diverse vendors.
• OSFP form factor and TAA compliance: Designed for hot-swapping in OSFP-compatible slots, this transceiver suits a wide array of data center devices. Its TAA-compliant construction ensures it meets government and enterprise procurement standards, giving organizations confidence in compatibility and traceability across the supply chain.
• Robust reliability and integration support: Built to operate in demanding data-center environments, the MMA4Z00-NS compatible transceiver emphasizes low latency, stable BER margins, and broad interoperability. It’s engineered to integrate smoothly with Mellanox ecosystems and other CMIS-compliant platforms, backed by comprehensive testing and documentation to simplify deployment and troubleshooting.

how to install Mellanox MMA4Z00-NS Compatible TAA 800GBase-2xSR4 PAM4 OSFP Transceiver

Follow these steps to install the transceiver safely and ensure optimal performance:

• Power down the switch or router that hosts the OSFP slot and remove the equipment from its rack to prevent electrostatic discharge.
• Identify a compatible OSFP slot that supports 800G PAM4 SR4 configurations and verify that the chassis and backplane are CMIS 5.0 compliant for best interoperability.
• Carefully remove the existing module (if replacing) by releasing the module latch and pulling straight out with steady, even force. Avoid twisting or pulling on cables attached to the module.
• Inspect the transceiver connector and the slot for any dust or debris. If necessary, clean with an approved blower and recheck alignment to ensure a smooth insertion.
• Slide the MMA4Z00-NS transceiver into the OSFP slot until it seats firmly with a click. Do not force insert; ensure the module is fully seated and parallel to the chassis faceplate.
• Connect the MMF fiber cables to the 2x MPO connectors, keeping fiber polarity correct to prevent link issues. Use the appropriate MTP/MPO breakout cables if your topology requires multiple lanes.
• Power up the device and monitor the DOM indicators or the management interface for link status, optical power, and temperature readings. Confirm that the 800GBase-2xSR4 PAM4 channels are online and that the link is stable.
• Verify the CMIS 5.0 compliance in your procurement catalog and ensure that the module is recognized by your network management system. Update any firmware or driver references if required by your management platform.
• Document the installation for asset tracking and support purposes, including serial numbers, firmware versions, and link performance metrics observed during initial bring-up.

Frequently asked questions

• Q: What does 800GBase-2xSR4 PAM4 mean?
  A: It refers to an 800 Gbps aggregate data rate achieved via two SR4 lanes using PAM4 signaling. PAM4 increases throughput per lane compared to NRZ, enabling higher total bandwidth over existing MMF infrastructure in a single OSFP module.
• Q: What fiber type and reach does this transceiver support?
  A: It is designed for multimode fiber (MMF) with an 850 nm wavelength and a reach of up to 50 meters, making it well-suited for intra-data-center links and mid-range campus deployments.
• Q: What is DOM, and why is it important?
  A: DOM stands for Digital Optical Monitoring. It provides real-time data on optical parameters such as Tx/Rx power and module temperature, helping operators monitor health, preempt failures, and simplify troubleshooting.
• Q: Is CMIS 5.0 compatibility important for procurement?
  A: Yes. CMIS 5.0 compliance ensures consistent cross-vendor interoperability, simplifies procurement workflows, and enables accurate cataloging and asset management across a diverse vendor ecosystem.
• Q: Is this transceiver compatible with systems other than Mellanox?
  A: The MMA4Z00-NS compatibility label indicates designed alignment with OSFP and CMIS 5.0 standards; it should work with OSFP-compatible devices that support 800G PAM4 SR4 interfaces and similar CMIS-compliant management interfaces. Always verify with your device vendor’s compatibility matrix.
