3.Core functional characteristics

Table 3: Detailed Function Explanation

Functional Module Technical Description System Value

Wavelength division multiplexing provides five sets of 1x2 couplers for multiplexing and demultiplexing of extended C-band signals, achieving the multiplexing and splitting of multi wavelength signals.It is the fundamental optical layer component of DWDM systems

Multi split ratio supports three sets of 50:50 couplers and two sets of 90:10 couplers to meet different application requirements.The 90:10 coupler can be used for monitoring ports to extract a small amount of optical power for monitoring without significantly affecting the main optical channel

Alarm and performance monitoring support the monitoring of board related alarms and performance events to quickly locate optical layer faults and improve network maintainability

Extended C-band coverage with a working wavelength range of 1528.8nm to 1567.6nm (Extended C-band) supports high-capacity DWDM systems with 96 wave @ 50GHz grids, meeting the demand for improving spectral efficiency

Passive design is mainly based on passive optocouplers to achieve ultra-low power consumption (1W), high reliability, and almost no need for heat dissipation considerations

6.Application scenarios

Table 7: Typical Application Scenarios

Core Value of Application Scenario Deployment Method

DWDM terminal station (OTM) is used in the terminal station to combine signals of multiple wavelengths into one path for transmission, or to decompose the received combined signal into a single wavelength as a multiplexer/demultiplexer, constructing the core optical layer of the DWDM system

Optical amplification station (OLA) is used in conjunction with optical amplifiers in line amplification stations to achieve power compensation of multi wavelength signals and provide multiplexing and demultiplexing functions, supporting long-distance transmission across multiple spans

The ROADM node serves as the fundamental optical layer multiplexing and division unit in the reconfigurable optical add/drop multiplexer node, providing the optical path foundation for wavelength level dynamic scheduling

The optical performance monitoring point utilizes the 10% monitoring port of the 90:10 coupler to connect to the optical performance monitoring unit (OPM) for uninterrupted online spectral monitoring of services, obtaining key parameters such as wavelength power and OSNR in real time

In the newly built extended C-band system, as a standard multiplexing component, it supports high-capacity systems with 96 wave @ 50GHz grids, maximizing fiber spectrum utilization

7.Maintenance and ordering information

Table 8: Maintenance and Ordering Points

Project Information

Component code TN97MD2 (specific version such as TN97MD201)

Ordering instructions: When ordering, please specify the board version.The MD2 board does not need to be configured with an optical module

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

Port 90:10 uses 10% branch ports (P42/P52) which can be used to connect monitoring devices.When using, pay attention to the input power range to avoid damaging the monitoring instrument

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

Spare parts management, as a standard optical passive board, has extremely high reliability.The proportion of spare parts can be appropriately reduced, but it is recommended to retain spare parts at critical nodes
