The NVIDIA/Mellanox Compatible QSFP112 InfiniBand NDR Optical Transceiver is an InfiniBand 400Gb/s Single-port QSFP112, XDR4 single-mode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Reach 4-channel (XDR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 2km using OS2 single mode fibers. It is qualified for use in InfiniBand NDR end-to-end systems.
It is the ideal solution for supercomputing, seamlessly integrating into computing and storage infrastructure to ensure efficient high-performance interconnectivity. Used in ConnectX-7/QSFP112 adapters linked to Twin-port transceivers in 2x400G IB switches.
