MMS4A20-XM800 Overview

NVIDIA MMS4A20-XM800 Single Port Transceiver 800gbps Osfp Dr4 Mpo Apc 1310nm Smf Up To 500m Rhs Overview The NVIDIA Mms4a20 Is An 800gb/s Single-mode Optical Transceiver Supporting The Xdr 800gb/s Infiniband Protocol. It Is Used To Link The Quantum-x800 Qm3x00 Switches Using Twin-port Osfp 2x800gb/s Transceivers To The Dual 800gb/s Connectx-8 Mezzanine Card In Liquid Cooled System And Connectx-8 Pcie Cards. Osfp Cages Are Located In The Compute Tray Front-panel. The Line Rate Is 200gb/s Using Pulse Amplitude Modulation Of 4- Channels Denoted As 200g-pam4, Enabling Two Data Bits To Be Transferred Per Clock Pulse. The Electrical Configuration Is 4-channels Of 200g-pam4. The Optical Configuration Has One, 500-meter, Datacenter Reach, 4-channel (dr4), 800gb/s Optical Connector, And Is A Single Multiple Push-on 12-fiber, Angled Polished Connector Or Mpo-12/apc. One Mpo-12/apc Optical Connector Is Used Per Transceiver. Based On 9-mm, Single Mode Fibers, The 800g Transceiver Can Reach Up To 500-meters, Supporting Large Gpu Clusters. The Plug Formfactor Is A Single-port Osfp (octal Small Formfactor Plug) And Uses A Riding Heat Sink (rhs) Or Flat-top Osfp Connector With The Cooling Fins On Top Of The Connectx-8 Cage. This Can Also Be Used In Liquid-cooled Riding Heat Sink (rhs) Applications. NVIDIAS Transceivers Guarantee Optimal Operation In NVIDIA End-to- End Infiniband Systems And Rigorous Production Testing Ensures The Lowest Bit Error Rates, Low-latency, And Best Out-of-the-box Installation Experience, Performance, And Durability.

The Nvidia MMS4A20-XM800 is a high-performance QSFP-DD transceiver designed for high-density data center networking. It facilitates rapid data transmission, enabling seamless connectivity for demanding applications such as AI clusters, cloud computing, and large-scale enterprise switching fabrics where high bandwidth and low latency are critical for maintaining network throughput and efficiency.
What cabling infrastructure is compatible with the MMS4A20-XM800? +
This transceiver is specifically engineered for high-speed fiber optic connectivity. It supports standard single-mode or multi-mode fiber interfaces depending on the specific optical requirements of your network architecture. By utilizing the QSFP-DD form factor, it ensures compatibility with advanced networking hardware that requires dense, high-capacity interconnects while maintaining the signal integrity needed for enterprise-grade data transmission over your existing fiber plant.
Can I use the MMS4A20-XM800 in a standard QSFP28 port? +
While the QSFP-DD form factor is designed to be backward compatible with QSFP28 cages, physical and electrical constraints may apply depending on your specific switch model. Always verify your switch's port power budget and software support before deployment. This module is optimized for QSFP-DD slots, ensuring it delivers the full performance specifications intended for modern, high-density network environments.
Is the MMS4A20-XM800 suitable for 400G network deployments? +
Yes, this module is an excellent choice for 400G network upgrades. It is designed to meet the rigorous demands of 400Gb/s Ethernet architectures. By providing a reliable, high-speed optical interface, it allows network administrators to scale their core and distribution layers effectively, handling massive traffic volumes characteristic of modern AI workloads and large-scale data center interconnections.
How does the MMS4A20-XM800 manage heat dissipation in high-density racks? +
The MMS4A20-XM800 incorporates advanced thermal management features inherent to the QSFP-DD standard. The module is engineered for efficient heat dissipation, which is vital when operating in densely packed switch line cards. This design prevents thermal throttling, ensuring that the transceiver maintains consistent performance metrics even during sustained periods of peak traffic load in demanding enterprise or service provider environments.
Does the MMS4A20-XM800 require specific software configuration on Nvidia switches? +
In most deployment scenarios, the module is recognized automatically by Nvidia networking hardware once inserted. However, you should ensure your switch firmware is updated to the latest version to support the specific transceiver profiles of the MMS4A20-XM800. Checking the software compatibility matrix ensures seamless initialization and enables the switch to correctly report optical diagnostic data, which is essential for ongoing performance monitoring.
What is the typical use case for this QSFP-DD transceiver in an AI data center? +
This module is frequently used in AI data centers to facilitate high-bandwidth links between compute nodes and leaf-spine switches. Its low-latency architecture supports the rapid movement of large datasets, which is necessary for machine learning model training and inference. By leveraging this transceiver, data centers can achieve the necessary speed and reliability required to eliminate network bottlenecks in compute-intensive environments.
Are there specific power requirements I should consider when installing the MMS4A20-XM800? +
The MMS4A20-XM800 operates within the established power envelopes for QSFP-DD transceivers. Because it is a high-performance component, it is essential to ensure that your switch or router ports are configured to provide sufficient power. Review your hardware specifications to confirm the power delivery capabilities of your chassis match the requirements of this module to ensure stable and long-term operation.
