NVIDIA MMS4A00-XM 1.6Tb/s 2-port OSFP Optical Transceiver

NVIDIA MMS4A00-XM is a 1.6Tb/s (1600Gbps) twin-port OSFP optical transceiver designed for high-density InfiniBand XDR networks. Unlike the single-port MMS4A20, this module combines two independent 800Gb/s DR4 optical engines within a single OSFP224 pluggable shell to maximize switch-port bandwidth density.
