NVIDIA InfiniBand MMS4X00-NS400 OSFP 400G DR4+ PAM4 1310nm 2km MPO-12/APC SMF NDR Flat Top Optical Transceiver Module for ConnectX-7 HCA
NVIDIA InfiniBand Compatible OSFP 400G DR4 PAM4 Optical Transceiver (SMF, 1310nm, 2km, MPO-12/APC, DOM, Flat Top)
The 400G DR4+ (also known as xDR4) OSFP Optical Transceiver is an InfiniBand 400Gb/s Single-port OSFP, DR4+ single mode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Reach 4-channel (DR4) 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/OSFP adapters linked to Twin-port transceivers in 2x400G IB switches.
The 2km 400G OSFP DR4+ part is similar to the 100-meter MMS4X00-NS400, only extensively tested up to 2km use cases and may employ a different error correction scheme.
