Brief Introduction
The NVIDIA InfiniBand MMA4Z00-NS400 Compatible OSFP Optical Transceiver is an InfiniBand 400Gb/s Single-port OSFP, SR4 multimode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Short Reach 4-channel (SR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using OM4 multimode 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/OSFP adapters linked to Twin-port transceivers in 2x400G IB switches.

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
