NVIDIA InfiniBand (800G)

Meets InfiniBand NDR end-to-end system requirements

Built-in Broadcom 7nm DSP chip, maximum power consumption is 16.5W

OSFP with top heatsink for Quantum-2 liquid-cooled switches

Supports 800G to 800G links between switches

Converts 8×100G-PAM4 electrical signals into 2×4×100G-PAM4 optical signals for multiplexing

Verified on real hardware to ensure full compatibility with NVIDIA QM9700/9790 devices

Complies with OSFP MSA, IEEE 802.3ck, RoHS standards and Class 1 laser safety, supports digital diagnostic monitoring (DDM/DOM)

This NVIDIA/Mellanox InfiniBand MMS4X50-NM compatible OSFP transceiver is an InfiniBand

800Gb/s 2x400Gb/s dual-port OSFP, 2xFR4 single-mode multiplexed optical module. It uses 2

fibers and 4-channel duplex LC optical connectors, each supporting 100G-PAM4 transmission.

The parallel short-reach 8-channel (2xFR4) design is based on CWDM4 serial multiplexing at the

1310nm wavelength grid, adopting the 100G-PAM4 electro-optic modulation format. It is designed

for InfiniBand NDR end-to-end systems. It is an ideal solution for supercomputing, enabling seamless integration into compute and storage

infrastructures to ensure efficient high-performance interconnection. It is intended for Quantum-2

liquid-cooled switches.
