1.Product Overview

TNU2N402 is an enhanced multi service 400G wavelength division multiplexing circuit board on the Huawei OSN 9800 series optical transmission platform.This board is located at the core of the urban area, the edge of the backbone network, and large aggregation nodes.On the basis of providing single wave 400G high-speed line transmission capability, it deeply integrates flexible OTN layer crossing and grouping enhancement processing functions, aiming to meet the comprehensive needs of multi service unified access, efficient aggregation, and flexible scheduling in complex network environments.It is the core component for building intelligent, integrated, and high-capacity optical transmission layers.

2.Core features and differentiated positioning

Unified access and aggregation of multiple services

Provide high-density multi-channel customer side service interfaces, supporting simultaneous access to multiple types and rates of customer signals, such as 100GE, 10GE, STM-N, OTU2/2e/4, etc., to achieve unified aggregation of services.

Powerful onboard processing capabilities enable efficient multiplexing and mapping of multiple low order services into high-order OTN containers (such as ODU4 and ODUCn), improving fiber bandwidth utilization.

Integrated OTN layer crossing and scheduling

The board is equipped with advanced OTN (ODUk/OSU) layer crossing units, which support flexible scheduling, routing, and protection of sub wavelength level services (such as ODU0/ODUflex/OSU) based on wavelength level transmission.

This feature makes network planning more flexible, enabling non blocking exchange of business within nodes and reducing dependence on external independent cross devices.

Grouping enhances processing capability

On the basis of traditional OTN bearer, it enhances the perception and processing capabilities of Ethernet services, supports basic grouping functions such as L2 switching, VLAN processing, QoS policies, etc.

It can better adapt to modern traffic models mainly based on IP/Ethernet, providing more refined business management and service quality assurance.

Intelligent and reliable 400G coherent transmission

Inherit the advanced 400G coherent optical transmission technology, support software definable modulation formats (such as 16QAM, 8QAM, QPSK), and adapt to different transmission distance requirements.

Integrate intelligent optical performance monitoring and fault diagnosis functions to ensure the stability and reliability of long-distance transmission.

4.Typical application scenarios

Urban core/backbone edge node: As a hub for business aggregation and scheduling, it terminates converged services from multiple directions and flexibly schedules them at the electrical layer before forwarding them to upstream core nodes via 400G wavelength.

Multi service integrated access point: In large data centers, it provides a unified access, aggregation, and transmission platform for different sources and protocols of services such as government enterprise dedicated lines, mobile backhaul, broadband access, etc.

Regional network hub: used in provincial or regional networks to achieve flexible exchange and diversion of traffic between different subnets, optimizing network structure.

Cloud network POP point: At the entrance of the cloud resource pool, it enables efficient aggregation of enterprise cloud dedicated lines and flexible connection directly to the cloud.

5.Summary of Core Values
