1.Product Overview

TNU3U401 is a high-performance compact 800G wavelength division multiplexing circuit board representing top engineering design on the OSN 9800 series optical transmission platform.This board challenges and breaks the traditional balance between high-density integration and extreme performance, integrating industry-leading 800G coherent transmission system within standard board size.It is designed specifically for ultra large scale data center interconnect (DCI) cores, high-end computing power cluster backbones, and high-density metropolitan core nodes that have extremely valuable space resources and strict requirements for single slot transmission capacity.It aims to deliver the maximum absolute transmission bandwidth with minimal physical space occupation and is a core density component for building future EB level data exchange networks.

2.Core Features and Engineering Breakthroughs

Ultimate space efficiency and performance density

By adopting revolutionary high-density optoelectronic collaborative design, advanced packaging, and efficient heat dissipation technology, all complex functional units required for high-performance 800G coherent transmission have been fully realized in a compact board space.

Its"performance/volume ratio" and"capacity/slot ratio" have reached industry-leading levels, enabling a leap in the total capacity of single cabinet systems and maximizing the spatial value of data centers and core data centers.

Top tier 800G transmission performance

Equipped with Huawei's latest generation of high-efficiency oDSP chips, it supports programmable high-order modulation formats (such as 64QAM/128QAM) and enhanced probability shaping technology.

Even in a compact design, it still maintains excellent transmission performance, supporting transmission distances from metropolitan DCI to regional backbone (supporting ≥400km in typical scenarios), meeting the stringent requirements of high-density core scenarios.

Optimization Design for High Density Interconnection

Optimize the traffic model for the internal and interconnected data centers and computing power centers, supporting ultra-low latency transmission and fast link establishment.

Fully supports FlexE (Flexible Ethernet) hard slicing, providing deterministic isolated sub channels for different businesses or tenants within a single physical channel.

Intelligent high-density operation and maintenance

Integrated high-precision environmental and performance sensors, supporting AI based board level health prediction and dynamic thermal management.

Deeply integrated with cloud based network management, supporting batch management and intelligent policy issuance for large-scale and high-density deployment of boards, reducing operational complexity.
