The NVIDIA/Mellanox InfiniBand MC2210411-SR4E Compatible QSFP+ Optical Transceiver is an InfiniBand 40Gb/s QSFP+, SR4 multimode parallel transceiver using a single, 4-channel MPO-12/UPC optical connector. The parallel multimode, short reach 4-channel (SR4) uses 10G-NRZ modulation and has a maximum fiber reach of 150-meters using OM4 multimode fibers. It is qualified for use in InfiniBand FDR10 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 SB7800/SB7890 switches and ConnectX-5 adapters.Because the QSFP-SR4-40G does not support 4x10G breakout connectivity, see QSFP-4×10G-SR for such applications.
