1.Product Overview

TNU2U401 is a compact universal 400G wavelength division multiplexing circuit board on the OSN 9800 series optical transmission platform.The board adopts high-density and integrated design, providing efficient 400G line side transmission capability within the standard board space, while maintaining good universality and scene adaptability.It aims to provide stable, reliable, and space saving basic transmission solutions for urban core edges, large aggregation nodes, and scenarios that require cost-effective 400G access.It is an ideal universal component for building dense wavelength division networks and achieving smooth network capacity upgrades.

2.Core Features and Value Positioning

Compact high-density design

By adopting advanced hardware integration technology, a complete 400G coherent optical transmission engine has been achieved within a compact board size.

High density design helps to improve the port capacity and total throughput of the entire equipment, especially suitable for scenarios such as data centers and core data centers with limited cabinet space or high requirements for single cabinet capacity.

Strong universality and flexible deployment

The design follows the general specifications of the platform, has good compatibility, and can be flexibly deployed in multiple sub rack slots of the OSN9800 platform.

Supporting standard 400G OTN line interfaces, it can collaborate with various customer side business boards within the platform, carrying mainstream services such as Ethernet and OTN, and has a wide range of application scenarios.

Mature and stable 400G transmission performance

Based on Huawei's mature 400G coherent transmission technology platform, it supports software configurable modulation formats (such as DP-16QAM) and can optimize performance according to transmission distance.

Provide stable and reliable 400G long-distance transmission capability (typical distance ≥ 400km) to meet the needs of urban and regional trunk applications.

Excellent overall cost of ownership

The high integration design reduces the power consumption and unit bit cost of the single board.

The universal design reduces the types of spare parts and operational complexity, providing excellent cost-effectiveness throughout the entire lifecycle from procurement, deployment to long-term operation and maintenance.
