Introduction
The NVIDIA/Mellanox MMS4A00-compatible OSFP optical module is an InfiniBand 1.6T 2x 800Gb/s dual-port OSFP optical module featuring 2xDR4/DR8 single-mode design based on silicon photonics technology. It utilizes a parallel 8-channel architecture and is equipped with two 4-channel MPO-12/APC optical connectors, each supporting a transmission rate of 800Gb/s. The parallel single-mode short-reach 8-channel (2xDR4/DR8) configuration employs 200G-PAM4 modulation technology, achieving a maximum fiber transmission distance of up to 500 meters over 8 single-mode fibers. This product complies with system requirements for InfiniBand XDR end-to-end systems.
The version with an integrated heat sink top cover (OSFP-IHS) is suitable for Quantum-X800 air-cooled and liquid-cooled switches. It represents an ideal solution for the supercomputing and high-performance computing (HPC) industry, seamlessly integrating into computing and storage infrastructures to ensure efficient high-performance interconnectivity. Primary applications include connections between two switches (up to 500 meters) or linking two 800G links to network adapters for storage and compute server interconnections.
Application Scenarios
1.6T to 1.6T Link for Switch-to-Switch Connections
1.6T to 2x800G Links for DGX B300
1.6T to 2x800G Links for Switch-to-Server Connections
Key Features
Broadcom 3nm DSP and SiPh Technology for Excellent Power Efficiency
Utilizing Broadcom's 3nm DSP and Silicon Photonics chips, this 1.6T XDR transceiver achieves a low power consumption of 25W (energy savings of over 25%) and an ultra-low bit error rate of 6E-12 (with FEC enabled). It supports higher port densities, reduces cooling requirements and total cost of ownership, and seamlessly integrates with DGX GB300/B300 to facilitate smooth scaling of AI clusters.
Efficiency Breakthrough for Hyperscale AI Clusters
The OSFP XDR solution utilizes 1.6T transceivers to enhance cluster energy efficiency through high bandwidth density and optimized link architecture. In a 512-node configuration, this solution delivers exceptional throughput, advanced scalability, significantly reduces energy consumption and space requirements, achieving a total cost reduction of 40.52%.
100% NVIDIA Environment Tested
The 1.6T OSFP DR8 module has been tested on original NVIDIA Quantum-X800 equipment to ensure the perfect integration of product performance and reliability. Testing covers hardware compatibility (plug/unplug, reboot) and software compatibility (connectivity, parameters). Compatibility can be verified through our optical module compatibility tool.
