NVIDIA MMS4X00-NS400 400Gb/s Single-portOSFP Single Mode DR4 Transceivers
The NVIDIA MMS4X00-NS400 is an InfiniBand (IB) and Ethernet (ETH) 400Gb/s, Single-port, OSFP, DR4 single mode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Datacenter Reach 4-channel (DR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 100-meters and assumes two optical patch panels in the link. It has identical design and internals as the QSFP112 version with different connector shells. The transceiver firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the connected switch. The OSFP shell has a flat-top and utilizes the riding heat sink (cooling fins) on the ConnectX-7 connector cage. When linked to 1:2 splitter fiber cable split end has only 2 channels and will activate…
