1.Product Overview

TNU3N402 is a high-performance, high-density single wave 800G coherent wavelength division multiplexing circuit board launched by Huawei OSN 9800 series optical transmission platform for data center interconnection and computing power networks.This board is deeply optimized for the needs of ultra-high bandwidth, ultra-low latency, and ultimate energy efficiency in modern large-scale data centers, artificial intelligence computing clusters, and"East West Computing" scenarios.It is the core engine for building high-speed, flexible, and green computing power optical networks, aiming to provide the best cost and power consumption per bit with industry-leading single wave 800G transmission capacity.

2.Core features and differentiated positioning

Ultimate single wave 800G performance and density

Supporting a single channel 800Gbps line rate and providing industry-leading transmission capacity within a single slot, it is an ideal choice for data centers to cope with burst traffic of up to 100 terabytes generated by AI model training, data lake synchronization, and other applications.

High density design maximizes the transmission capacity of a single cabinet, effectively reduces the occupation of data center space, and conforms to the trend of high-density deployment in data centers.

Deep optimization for DCI scenarios

Ultra low latency design: adopting optimized hardware architecture and signal processing algorithms to minimize transmission latency, meeting the strict requirements of latency sensitivity in financial transactions, AI collaborative computing, and other fields.

High power budget and simplified design: Enhance transmit optical power and receive sensitivity, support longer relay free transmission distances (typical 80-120km), reduce relay stations, and achieve simplified point-to-point or ROADM networking.

Intelligent rapid deployment: supports zero contact activation and one click debugging, significantly reducing business launch time and adapting to the rapid iteration needs of data centers.

Advanced coherent transmission and spectral efficiency

Equipped with Huawei's latest generation of high-efficiency oDSP chips, it supports programmable ultra-high order modulation formats (such as 128QAM, 64QAM) and enhanced probability shaping technology, achieving spectrum efficiency close to theoretical limits within the metropolitan DCI distance.

Having excellent nonlinear compensation capability and anti damage performance, ensuring stable operation in complex fiber optic environments.

Openness and flexibility towards computing power networks

Fully supports FlexE (Flexible Ethernet) hard slicing technology, providing dedicated channels with physical isolation and flexible bandwidth adjustment for different computing tasks or tenants.

Collaborating with Huawei's all-optical switching OXC technology, it supports dynamic and flexible scheduling at wavelength and sub wavelength levels, meeting the needs of dynamic connections after computing resource pooling.

Support smooth expansion to C-band and C+L band, leaving sufficient space for future capacity growth.
