7.Application scenarios

Core Value of Application Scenario Deployment Method

The receiving end of the extended C-band ROADM node is used as a downlink unit in the ROADM node, and WSS is used to achieve colorless downlink support for the extended C-band 96 wave system, achieving high-density wavelength level flexible scheduling

Deploying pure passive design, zero power consumption, and high reliability for local business broadcast distribution in scenarios where signals need to be broadcasted to multiple local receivers

Optical layer ASON network nodes serve as downstream units in networks that require optical layer intelligence features.Optical layer ASON supports automated business scheduling and protection

Space constrained nodes are deployed in sites with tight cabinet space, featuring a 25.4mm ultra-thin design that is only 1U wide, saving subrack slots

8.Maintenance and ordering information

Project Information

Component code TN97TD20

Ordering instructions: Please confirm the working band (extended C-band) when placing an order

On site operation supports hot plugging, and anti-static wrist straps should be worn during operation.Pay attention to cleaning the fiber optic connectors

Test and verify that insertion loss testing and port connectivity testing are required after installation

Spare parts management, as a passive component, has high reliability and can appropriately reduce the proportion of spare parts, but key nodes can be configured with spare parts

Warranty service standard: The warranty period is 1 year, and technical support can be obtained through authorized Huawei distributors

Core Summary:

TN97TD20 is a 20 port tunable demultiplexing board for extended C-band high-density DWDM systems in the OSN 9800 platform.Based on a pure passive 1x20 splitter design, it achieves colorless downlink of 20 coherent wavelength signals.

Core values and positioning:

High density colorless downlink core component: supports up to 20 coherent wavelength signals for broadcast downlink, and any wavelength can be downlink from any DM port, greatly improving network configuration flexibility.

Extended C-band support: The working wavelength covers 1528.8-1567.6nm (Extended C-band) and can carry high-density DWDM systems with 96 waves @ 50GHz.It is compatible with the Huawei OSN 9800 platform Super C+Super L evolution route.

Ultra low power consumption and high reliability: Based on pure passive spectral design, the power consumption is only 1.0W, without the need for heat dissipation, with extremely high reliability and long service life.

Compact design saves space: The 25.4mm ultra-thin front panel (1U wide) saves 50% of slot space compared to the TN12TD20 (2U wide).

Optical Layer ASON Intelligent Support: Supports automatic switching of optical network functions at the optical layer, providing a foundation for intelligent optical networks.

Differences in positioning compared to TN12TD20:

Dimension TN97TD20 TN12TD20

Design concept: pure passive, high-density, ultra-low power active integration (EDFA+VOA), power adjustable

Applicable scenarios: Loss sensitive scenarios that require gain compensation in the C-band conventional power channel

Space efficiency 25.4mm (1U width) 50.8mm (2U width)

Power consumption cost of 1.0W, extremely low operating cost of 13.0W, heat dissipation needs to be considered

Application suggestion:

This board is the downlink core component of the OSN 9800 wavelength division system for the extended C-band high-density ROADM network. It is particularly suitable for scenarios that require high-density colorless downlink, extended C-band support, limited space, and low power consumption, such as backbone network core hub nodes, multi-directional service aggregation nodes, etc. When deploying, it is necessary to combine the iMaster NCE intelligent control system to build a high-density, highly reliable, and reconfigurable intelligent optical layer network. For nodes that require gain compensation and power adjustment, TN12TD20 is a more suitable choice.
