The NVIDIA/Mellanox InfiniBand MMS4X00-NM Compatible OSFP Optical Transceiver is an InfiniBand 800Gb/s 2x 400Gb/s Twin-port OSFP, DR8 single mode, parallel, 8-channel transceiver using two, 2-fiber, 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel single mode, reach 8-channel (DR8) design uses 100G-PAM4 modulation and has a maximum fiber reach of 500-meters using 8 single mode fibers. It is qualified for use in InfiniBand NDR end-to-end systems.
The twin-port OSFP closed finned top transceiver is used in Quantum-2 air-cooled switches. Featured with low latency, low power, and reliability, it can link upward in spine-leaf architectures for switch-to-switch applications, downward for top-of-rack switch links to ConnectX® smart network adapters, and/or to BlueField-3 DPUs in compute servers and storage subsystems. It is the ideal solution for HPC computing, AI, and cloud data centers.
Note: This "Closed Finned Top" refers to a closed top design, which uses a finned-top but with a lid on top of the fins creating a closed channel for additional cooling. It is engineered to support both airflow cooling and liquid-cooled environments, offering enhanced mechanical protection and thermal compatibility in high-density systems.
