Description
The Mellanox T-DQ8FNS-N00-M is a cutting-edge QSFP-DD (Quad Small Form-factor Pluggable Double Density) optical module designed to deliver ultra-high-speed connectivity at 400 Gigabit Ethernet. This module utilizes 8 parallel lanes, each operating at 50Gb/s with PAM4 modulation, to achieve its aggregate 400Gb/s throughput. It is specifically engineered for short-reach applications within data centers, high-performance computing (HPC) clusters, and artificial intelligence (AI) / machine learning (ML) environments where massive data movement is critical. The 400GBASE-SR8 standard indicates that this module is designed for parallel optics over multimode fiber (MMF). It typically uses an MPO (Multi-fiber Push On) connector, which accommodates multiple fiber strands required for the parallel transmission. This configuration allows for high-density cabling and efficient use of rack space in demanding data center deployments. As part of NVIDIA's (formerly Mellanox) networking portfolio, the T-DQ8FNS-N00-M is optimized for performance, low latency, and power efficiency. Its QSFP-DD form factor provides higher port density compared to traditional QSFP28 modules, enabling more connections within the same physical space. The hot-pluggable nature of the module ensures ease of installation and maintenance, crucial for maintaining uptime in mission-critical data center operations. This module is a key enabler for next-generation data center networks requiring extreme bandwidth.
