NVIDIA/Mellanox MMS4A00 Compatible 1.6T 2 x DR4/DR8 OSFP224 IHS/Closed Finned Top 8 x 200G PAM4 1310nm 500m Dual MPO-12/APC SMF InfiniBand XDR Transceiver Module
Overview
The NVIDIA/Mellanox MMS4A00 compatible OSFP224 optical transceiver is a twin-port module designed for InfiniBand XDR network architectures. It delivers 1.6Tb/s aggregate bandwidth by providing 2 x 800Gb/s connections. Utilizing silicon photonics-based architecture and a 3nm Broadcom DSP, the module supports 8-channel parallel transmission over single-mode fiber with 200G-PAM4 electrical modulation.
Key Features
- Integrated Heat Sink (IHS) Design: Features an integrated closed finned top for thermal management, compatible with standard air-cooled switch environments.
- Broadcom 3nm DSP Integration: Utilizes advanced 3nm digital signal processing to facilitate 8x 200G-PAM4 modulation for high-speed data delivery.
- Dual MPO-12/APC Connectivity: Each of the two 800G ports utilizes a dedicated MPO-12/APC interface for connection to single-mode fiber infrastructure.
- Silicon Photonics Technology: Implements a SiPh-based optical design to maintain high port density and efficient signal transmission at 1310nm.
- InfiniBand XDR Compatibility: Engineered specifically for compatibility with NVIDIA Quantum-X800 switches and DGX GB300/B300 systems.
