Product Description

1. Product Overview

TNU1N402 is a highly integrated and compact 400G wavelength division multiplexing board on the Huawei OSN 9800 series optical transmission platform.This board is designed specifically for network edge, metropolitan aggregation, and cost-effective access scenarios.Through highly integrated design, it combines customer side business processing and line side transmission functions into one, achieving complete functionality from customer business access to wavelength division multiplexing transmission on a single board.It effectively saves data center space, reduces power consumption, and overall deployment costs, making it an ideal choice for building simplified, efficient, and flexible metropolitan optical networks.

2.Core features and differentiated positioning

High integration compact design

Single board integration of customer side business adaptation (such as Ethernet, OTN mapping) and 400G coherent optical transmission function on the line side, without the need for additional configuration of independent customer side business processing boards.

Greatly saves equipment slot and rack space, especially suitable for network edge nodes with limited space and power consumption (such as aggregation rooms, large enterprise access points).

Support CPE and Muxponder application modes

CPE (Client Equipment) mode: It can be directly placed in the customer data center or computer room as the customer side terminal of the wavelength division network, realizing the"one jump to the cloud" or transparent transmission of business, simplifying the stacking of customer side equipment.

Muxponder mode: On the operator's network side, multiple low speed customer services (such as 4x100GE, 10x40GE) can be multiplexed and converted to a 400G line wavelength, achieving business aggregation and efficient bandwidth utilization.

Flexible and configurable 400G transmission

It supports single channel 400G line rate, and can be configured into multiple modulation formats in software to adapt to different transmission distances.

By adopting high-performance coherent technology, stable and reliable 400G transmission can be achieved within a limited transmission budget (usually for metropolitan areas ranging from 80km to several hundred kilometers).

Simplified operations and maintenance for business agility

The plug and play design simplifies the installation and activation process.

A unified network management interface can simultaneously manage customer side business and line side optical layer parameters, reducing operational complexity.

4.Management and Operations

Management interface: Supports unified management through the main control board.

Performance monitoring: Simultaneously monitor customer side business performance (such as bit errors and packet loss) and line side optical performance (such as OSNR and optical power).

Alarm and diagnosis: Provide end-to-end fault location information.

Network management support: compatible with Huawei iManager NCE/U2000 series network management systems.

4.Typical application scenarios

Metropolitan/Regional Network Aggregation Layer: In the aggregation room, business traffic from multiple access rings is converged onto a 400G wavelength and uploaded to the core node.

Large enterprise/park dedicated line access: deployed as a CPE on the enterprise side, directly connected to the operator's wavelength division network through a fiber optic wavelength, providing enterprises with ultra-high bandwidth dedicated lines (such as 400GE dedicated lines).

Data Center Interconnection (DCI) Access Layer: Used to connect data centers within the same city or in close proximity, providing a concise and efficient 400G interconnection solution.

5G bearer network (backhaul aggregation): Aggregate a large amount of 5G base station backhaul traffic, which is transmitted upstream to the core router through high-speed wavelength.

5.Summary of Core Values

Space and cost savings: Integrated design reduces the number of required boards, lowers equipment procurement, installation, and maintenance costs.

Agile deployment: Simplify network hierarchy, accelerate business activation speed, especially suitable for fast response dedicated line services and cloud access services.

Flexible application: CPE and Muxponder dual-mode support enable it to be used on both the network and customer sides, providing flexible application.

Smooth Evolution: As a 400G access layer solution for the OSN9800 platform, it can seamlessly collaborate with higher speed backbone cards within the platform.

6.Ordering and Configuration Instructions

Basic board model: TNU1N402.

Usually, a designated model of CFP2 coherent optical module needs to be selected separately.

The specific specifications of customer side business interfaces (such as interface types and quantities) may vary depending on hardware versions or software licenses, and need to be clarified at the time of ordering.

Before deployment, it is necessary to plan the application mode (CPE or Muxponder) and configure the corresponding software functions.
