Interface Identification Interface Type Quantity Function Description

MON LC/UPC 1 monitoring port, coupled with approximately 1% to 2% of optical signals, used for online optical performance monitoring

3.Core functional characteristics

Functional Characteristics Technical Description System Value

Wavelength demultiplexing is based on array waveguide grating (AWG) technology, which separates the multiplexed signal into 48 single wavelength signals according to wavelength to achieve wavelength division at the DWDM receiving end.It is the core optical layer component

Flexible grid supports channel spacing of 50GHz or 100GHz, complies with ITU-T G.694.1 standard to adapt to systems with different channel spacing, and supports higher density wavelength division multiplexing (such as 96 wave systems)

Extended C-band coverage for working wavelengths (1528.8nm-1567.6nm) supports more wavelength channels to meet the demand for improving spectral efficiency

Low insertion loss optimized AWG design and low loss optical fiber minimize demultiplexing insertion loss, reduce the consumption of system optical power budget, and improve transmission distance

High isolation adjacent channel isolation typical value>28dB, non-adjacent>40dB effectively suppresses inter channel crosstalk, ensures signal quality, and supports long-distance transmission

The integrated monitoring port is equipped with a 1 ×2 splitter, which couples approximately 1% to 2% of the signal to the MON port, without affecting the main channel to achieve uninterrupted online spectral analysis and optical performance monitoring, facilitating network maintenance and optimization

4.Optical performance parameters

Consistency: The difference in insertion loss between each channel is ≤ 1.5 dB, ensuring power balance at the receiving end of each channel

Adjacent channel isolation ≥ 25 dB to suppress adjacent channel crosstalk

Non adjacent channel isolation interval ≥ 2 channels ≥ 35 dB provides higher isolation

Polarization related loss for all channels, with a full temperature range of ≤ 0.3 dB, insensitive to polarization, suitable for high-speed coherent optical modules

Return loss of all ports ≥ 45 dB to reduce reflection

6.Application scenarios

Core Value of Application Scenario Deployment Method

The high-density DWDM terminal station (OTM) separates the line side multiplexed signal into multiple receivers at the receiving end of the 96 wave/120 wave system to achieve the reception of high-density multi wavelength signals and maximize fiber utilization

The core/aggregation layer wavelength division network demultiplexing the multiplexed signal at the core node to different directions or business boards to support the receiving end wavelength division requirements of large-scale wavelength division networks

Data Center Interconnection (DCI) provides a high-capacity DCI interconnect receiving solution by splitting the multiplexed signal to switches in different data centers at the DCI receiving end

ROADM nodes are used in conjunction with WSS (wavelength selective switch) to demultiplexing specific wavelength groups to local ports, expanding ROADM's port density and supporting more wavelength up and down channels

Online spectral monitoring points use MON ports to connect optical performance monitoring units (OPMs) or spectral analyzers for real-time monitoring of channel power, wavelength offset, and OSNR, achieving optical layer visualization

7.Maintenance and ordering information

Project Information

Component code TN97D48 (refer to template, specific subject to actual situation)

Ordering instructions: When placing an order, it is necessary to confirm the channel spacing (50GHz/100GHz), wavelength range (extended C-band), and whether the MON port is included

Port identification: Each channel port is usually labeled with a wavelength tag that matches the wavelength of the transmitter

On site operation supports hot plugging, and anti-static wrist straps must be worn during operation to keep the fiber end face clean

After testing and verifying installation, insertion loss testing and connectivity testing of each channel are required.If necessary, a spectrometer should be used to verify the output spectra of each channel

As a passive component, the spare parts strategy has high reliability, but critical nodes can be configured with spare parts for quick recovery

Core Summary:

TN97D48 (reference template) is a 48 channel DWDM demultiplexing board for high-density wavelength division systems in the OSN 9800 platform.It uses array waveguide grating (AWG) technology to achieve demultiplexing of extended C-band signals.

Core values and positioning:

High density demultiplexing: 48 channel design, supporting 50GHz or 100GHz channel spacing, suitable for high-density DWDM system requirements such as 96 waves/120 waves, maximizing fiber spectrum utilization
