1.Product Overview

TNU2N401P is a standard economical single wave 400G coherent wavelength division multiplexing circuit board on the Huawei OSN 9800 series optical transmission platform.This board is optimized and designed based on Huawei's mature 400G transmission technology platform, aiming to provide stable, reliable, and cost-effective basic 400G line side transmission capabilities for urban core, regional trunk, and large aggregation nodes.It focuses on meeting the widest range of 400G bandwidth requirements, providing proven transmission performance at optimized costs, and is the mainstream economic choice for customers to evolve their networks towards 400G scale or build cost-effective 400G layers.

2.Core Features and Value Positioning

Economically efficient 400G access solution

By optimizing the architecture and design while ensuring core transmission performance and reliability, a better total cost of ownership (TCO) has been achieved, reducing the deployment threshold for 400G networks.

Providing excellent cost per bit is a cost-effective foundational component for building and scaling 400G backbone transmission planes.

Mature and reliable transmission platform

Inheriting Huawei's widely deployed 400G coherent technology, adopting rigorously validated hardware platforms and stable software systems to ensure carrier grade equipment reliability.

Supporting basic and efficient modulation formats (such as DP-16QAM), performance optimization has been carried out for typical metropolitan and regional transmission distances to ensure stable operation in the target scenario.

Standardized functionality and ease of integration

Provide standardized 400G OTN line interface functionality to support reliable transmission of mainstream customer side services (via business boards).

The design follows platform specifications and is fully compatible with the OSN9800 system's backplane, power supply, and management plane.The installation and deployment process is standardized and easy to integrate into existing or new networks.

Clear and smooth evolutionary path

As a basic 400G member of the platform, it can be mixed with other speed cards (such as 100G, 200G, 800G) to form a network, supporting flexible and phased capacity upgrades according to traffic growth, and protecting long-term investments.
