Description
The NVIDIA MMA4Z00-NS-FLT is a twin-port 800Gb/s (2x NDR) OSFP multimode transceiver. It operates at 850nm with dual MPO-12/APC connectors and reaches up to 50m. The flat-top version is designed for DGX H100 "Cedar" 800G links and liquid-cooled systems, where finned-top modules do not fit. It uses 8x 100G-PAM4 signaling and cannot downshift to 4x 50G-PAM4, so it does not link to HDR transceivers.
