NVIDIA/Mellanox MMS4X00-NM Compatible 800G OSFP DR8 PAM4 NDR InfiniBand Optical
Transceiver (2x DR4, 1310nm, 500m, Dual MPO-12/APC, DOM, with Top Heatsink)
This NVIDIA/Mellanox InfiniBand MMS4X00-NM compatible OSFP transceiver is an InfiniBand 800Gb/s
2x400Gb/s dual-port OSFP, a DR8 parallel 8-channel optical module. It uses 2 fibers and 4‑channel
MPO‑12/APC optical connectors, each supporting a data rate of 400Gb/s. The parallel short‑reach
8‑channel (DR8) design adopts 100G‑PAM4 modulation, with a maximum transmission distance of
500m over 8 single‑mode fibers. 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.
