MMS4X00-NM-HGX 800Gbps Twin-port OSFP 2x400Gb/s InfiniBand and Ethernet Single Mode 2xDR4 500m

Introduction

The NVIDIA MMS4X00-NM-HGX is an Ethernet 800Gb/s optical transceiver designed for Rubin NVL8 Systmes. The transceiver is a 2x400Gb/s Twin-port OSFP, 1310nm SMF (Single-Mode Fiber), 2xDR4 single mode, parallel 8-channel transceiver, using two 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel single mode, datacenter reach 8-channel (2xDR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 500-meters using 8 single mode fibers. The 500-meter length assumes two optical patch panels in the link.

The main application for MMS4X00-NM-HGX is linking RUBIN NVL8 to Spectrum-4 and Spectrum-5 switches.

The transceiver combinations guarantee optimal operation in NVIDIA end-to-end Ethernet systems and a rigorous production tested to ensure the best out-of-the-box installation experience, performance, and durability.
