3.Core functional characteristics

Functional Characteristics Technical Description System Value

Wavelength multiplexing is based on array waveguide grating (AWG) or configurable optical filtering technology, which synthesizes 40 different wavelength optical signals into one for transmission, achieving single fiber transmission of multi wavelength signals.It is the core transmitting component of DWDM systems, greatly improving fiber utilization efficiency

Flexible grid supports fixed spacing of 50GHz/100GHz and flexible grid adjustment of 37.5GHz~200GHz, complying with the ITU-T G.694.1 standard flexible grid specification to adapt to systems with different channel spacing.It supports coexistence of mixed rates (10G/40G/100G/200G) to maximize spectrum utilization efficiency

Extended C-band coverage for working wavelengths (1528.8nm-1567.6nm) supports flexible configuration of 40 channels and can be extended to more wavelength channels to meet the demand for improving spectral efficiency

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

High isolation between adjacent and non adjacent channels has excellent isolation characteristics, effectively suppressing inter channel crosstalk, ensuring signal quality, and supporting long-distance transmission

Passive design is entirely based on passive optical components to achieve functionality, without the need for power supply, zero power consumption, and zero heat generation.It has extremely high reliability and long service life, without the need for heat dissipation considerations

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

6.Application scenarios

Core Value of Application Scenario Deployment Method

In the ROADM network supporting Flex Grid, the flexible grid DWDM system serves as a standard uplink multiplexing unit in conjunction with a wavelength selective switch (WSS) to achieve flexible wavelength scheduling and spectrum allocation, supporting coexistence of mixed rate services

The DWDM terminal station (OTM) transmitter synthesizes single wavelength signals from 40 transmitters into one output at the OTM station, which supports flexible grid configuration and adapts to the spectrum requirements of future network evolution towards over 100G/400G

The core/aggregation layer wavelength division network aggregates multiple 10G/40G/100G/200G services at the core node onto the same fiber to maximize fiber spectrum utilization, reduce transmission costs per bit, and support multi rate hybrid transmission

Data Center Interconnection (DCI) provides a high-capacity, low-cost DCI interconnection solution at the data center exit, which combines wavelengths from multiple machine rooms and transmits them to remote data centers to meet future 400G/800G requirements

Fixed OADM nodes, in conjunction with OADM boards, insert local business wavelengths before combining to achieve fixed wavelength on road functionality, flexible networking, and support for flexible grid planning

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 TN11M40V (specific versions such as TN11M40V01, etc.)

Ordering instructions: When placing an order, it is necessary to confirm the flexible grid support range, working band, and whether the MON port is included

The standard configuration for connector selection is LC/UPC, supporting customized options such as LC/APC, SC/UPC, etc

Port identification: Each channel port needs to be accurately matched with the transmitter wavelength based on flexible grid planning

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 composite spectrum

As a passive component, the spare parts strategy has extremely high reliability and can reduce the proportion of spare parts appropriately.However, critical nodes can be configured with spare parts for quick recovery

Application suggestion:

This board is the core multiplexing component for flexible optical networks in the OSN 9800 wavelength division system, particularly suitable for ROADM networks that require flexible spectrum allocation and multi rate hybrid transmission, as well as newly built flexible grid DWDM systems. During deployment, flexible grid configuration should be planned based on the system channel spacing, and the optical performance monitoring unit should be connected to the MON port to construct a visualized intelligent optical layer. When used in conjunction with a demultiplexing board that supports flexible grids (such as TN11D40V), a complete flexible grid 40 wave DWDM transceiver system can be formed.
