The NVIDIA InfiniBand MMA1L30-CM Compatible QSFP28 Optical Transceive is a single mode, 4-channel (CWDM4), QSFP28, optical transceiver designed for use in 100Gb/s InfiniBand links on up to 2km of single mode fiber. The module converts 4 input channels of 25 Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single fiber, using a nominal wavelength of 1310 nm, for 100 Gb/s optical transmission. Reversely on the receiver side, the 100 Gb/s optical input is demultiplexed into 4 channels of CWDM optical signals and then converted to 4 output channels of electrical data. It is qualified for use in InfiniBand EDR 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.
Note: The FS P/N is changed from QSFP28-IR4-100GE to QSFP-CWDM4-100G, but the product is the same. Only the FS P/N has been changed.
