The SFPPlaza NVIDIA/Mellanox MMS4X00-NS (980-9I30H-00NM00) Compatible 800G 2xDR4 OSFP Optical Transceiver Module is designed for high-performance InfiniBand NDR networking, AI data centers, and hyperscale computing infrastructure. Featuring a Twin-Port OSFP form factor with an IHS/Closed Finned Top thermal design, this module delivers an aggregate bandwidth of 800Gb/s through two independent 400G DR4 optical interfaces, providing high-density connectivity for next-generation HPC and AI networking environments.
Operating at a nominal wavelength of 1310nm, this optical transceiver supports transmission distances of up to 100 meters over single-mode fiber (SMF). It utilizes 8x100G PAM4 signaling, with four 100G PAM4 optical lanes per 400G port. Two MPO-12/APC optical connectors provide independent connectivity for the dual 400G DR4 interfaces, enabling flexible 2x400G optical links and high-bandwidth 800G interconnections.
Designed for NVIDIA/Mellanox networking platforms, this MMS4X00-NS compatible transceiver is intended for supported NVIDIA Quantum-2 QM9700/QM9790 and Spectrum-4 air-cooled switches. Its dual-port architecture enables efficient 400G port aggregation, supporting high-density switch-to-switch interconnections and compatible breakout applications involving ConnectX-7 network adapters and BlueField-3 DPUs. This architecture helps optimize optical port utilization, reduce cabling complexity, and support scalable InfiniBand NDR network deployments.
The integrated heat sink (IHS) with Closed Finned Top construction is engineered to enhance thermal dissipation by increasing the effective cooling surface area. This design supports stable operating temperatures in high-density, high-speed networking environments and is suitable for compatible air-cooled switch platforms. DOM (Digital Optical Monitoring) enables real-time monitoring of key optical and operational parameters, facilitating network diagnostics and maintenance. The module is designed in accordance with OSFP MSA and CMIS 4.0 requirements and complies with RoHS environmental standards.
With its dual 400G DR4 optical architecture, 8x100G PAM4 signaling, 1310nm single-mode transmission, and advanced Finned Top thermal design, the SFPPlaza 800G 2xDR4 OSFP optical transceiver provides a reliable connectivity solution for InfiniBand NDR networks, AI training clusters, HPC infrastructure, and high-performance data center interconnects.
