Description

NVIDIA/Mellanox MMS4A00 (980-9IAH0-00XM00) Compatible 1.6T 2xDR4/DR8 InfiniBand XDR Silicon Photonics Optical Transceiver Module (Twin-port OSFP224, Broadcom 3nm DSP | Sian3 BCM83628, 1310nm, 500m (OS2) , Dual MPO-12/APC, DOM, SMF, RHS/Flat Top)

NADDOD OSFP-1.6T-2DR4FH Optical Transceiver is an InfiniBand and Ethernet 1.6Tb/s 2x800Gb/s Twin-port OSFP224, 2xDR4/DR8 single mode, Silicon photonics-based, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 800Gb/s each. The parallel single mode, data center reach 8-channel (2xDR4/DR8) design uses 200G-PAM4 modulation and has a maximum fiber reach of 500-meters using 8 single mode fibers.

Questions & Answers

Ask a Question

What are the differences between 1.6T finned top and flat top transceivers?

The Finned Top (IHS) version has metal heat-dissipating fins on top, ideal for air-cooled architectures with excellent thermal performance. The Flat Top (RHS) version has a completely flat top without fins, designed for liquid-cooled cold plate compression cooling scenarios.

Can the IB 1.6T 2xDR4 OSFP224 flat top transceiver be used with NVIDIA QM9700 switches?

No. The transceiver and the switch have mismatched SerDes speeds and form factor requirements. The QM9700 features 8x100G SerDes, while the 1.6T 2xDR4 transceiver features 8x212G SerDes. What's more, the QM9700 only supports finned top transceivers, but this model features a flat top design, making the two incompatible.

Is the 1.6T Flat Top transceiver compatible with air-cooled platforms?

No. The Flat Top transceiver has no active heat dissipation structure and relies on cold plate heat conduction, so it is only suitable for liquid-cooled architectures. Air-cooled platforms only support the Finned Top version.
