Company Introduction
This NVIDIA Mellanox InfiniBand MMA4Z00-NS400 compatible OSFP optical module is an InfiniBand
400Gb/s single-port OSFP112 SR4 multimode parallel optical transceiver, utilizing a single 4-channel
MPO-12/APC optical connector. The short-reach 4-channel (SR4) design adopts 100G-PAM4 modulation, with a maximum transmission distance of 50m over OM4 multimode fiber. It is suitable
for InfiniBand NDR end-to-end systems. It is an ideal solution for supercomputing, enabling seamless integration into compute and storage
infrastructures to ensure efficient high-performance interconnection. It is used for connecting
ConnectX-7 OSFP network adapters and 2×400G InfiniBand switches with dual-port optical modules.
