Company Introduction
This NVIDIA/Mellanox compatible QSFP112 NDR InfiniBand transceiver is an InfiniBand 400Gb/s
single-port QSFP112 FR4 single-mode parallel optical module with a single 4-channel duplex
LC/UPC optical connector. Featuring a short-reach 4-channel (FR4) design with 100G-PAM4
modulation, it supports transmission distances of up to 2km over OS2 single-mode fiber. The
module is used to connect ConnectX-7/QSFP112 network adapters and 2×400G InfiniBand
switches with dual-port optical modules. It is an ideal solution for supercomputing, designed for InfiniBand NDR end-to-end systems,
enabling seamless integration into compute and storage infrastructures to ensure efficient,
high-performance interconnection.
