3.Core functional characteristics

Functional Characteristics Technical Description System Value

Wavelength multiplexing is based on array waveguide grating (AWG) or thin film 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

100GHz spacing supports grid according to ITU-T G.694.1 standard, channel spacing of 100GHz, covering C-band and supporting 40 wave standard DWDM system, ensuring wavelength compatibility with demultiplexing boards, repeaters and other equipment

Low insertion loss optimized optical design and low loss fibers minimize the multiplexing insertion loss, reduce the pressure on the system's optical power budget, and extend the 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

4.Optical performance parameters

Parameter condition specification remarks

Working wavelength range -1529.16 nm~1560.61 nm (C-band) corresponds to the ITU-T 100GHz spacing standard, typically channels 20~59

Channel spacing -100 GHz compliant with ITU-T G.694.1 standard grid

Insertion loss for all channels, including connectors ≤ 5.0 dB (typical value), including losses from the combiner itself and connectors

Consistency: The insertion loss difference between each channel is ≤ 1.5 dB to ensure power balance at the transmitting end of each channel and avoid OSNR degradation in some channels

Isolation between adjacent channels ≥ 25 dB to suppress crosstalk between adjacent wavelengths

Non adjacent channel isolation ≥ 30 dB provides higher wavelength isolation

Polarization related loss ≤ 0.3 dB for all channels, insensitive to polarization effects, suitable for high-speed coherent optical modules

Return loss: All ports have excellent return loss characteristics of ≥ 40 dB, reducing the impact of reflection on the laser

Directionality - ≥50 dB to prevent reverse light interference

MON port coupling ratio -1%~2% (typical value) monitoring port power ratio, with negligible impact on the main channel

Power consumption 0 W (passive design, no power supply required)

Working temperature -5°C to+55°C

Storage temperature -40°C to+70°C

Relative humidity 5% to 95% RH, no condensation

Air pressure requirement: 70 kPa to 106 kPa

6.Application scenarios

Core Value of Application Scenario Deployment Method

The DWDM terminal station (OTM) transmitter synthesizes single wavelength signals from 40 transmitters into one output to the line for single fiber transmission of multi wavelength signals in the OTM station, which is a standard transmitter configuration

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

Data Center Interconnection (DCI) provides a high-capacity, low-cost DCI interconnection solution by multiplexing wavelengths from multiple machine rooms at the data center exit and transmitting them to remote data centers

In the 5G backhaul network, the 5G carrier network aggregates the service wavelengths of multiple base stations and connects them to the backbone layer to meet the high bandwidth backhaul requirements of the 5G era, simplifying the network hierarchy

Fixed OADM nodes, in conjunction with OADM boards, insert local business wavelengths before combining to achieve fixed wavelength uplink functionality, allowing for flexible networking

7.Maintenance and ordering information

Project Information

Component code TN11M40 (specific version as TN11M4001)

Ordering instructions: When placing an order, it is necessary to confirm the channel spacing (100GHz), wavelength range (C-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 is usually labeled with a wavelength tag (such as CH20 corresponding to 1560.61nm), which needs to match 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 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

Core Summary:

TN11M40 is a 40 channel DWDM combiner board in the OSN 9800 platform, which uses array waveguide grating (AWG) technology to achieve 40 channel signal combiner function with a spacing of 100GHz in the C-band.Its low insertion loss (≤ 5dB), high isolation (adjacent ≥ 25dB), and passive design with zero power consumption make it the core optical layer component for building highly reliable and high-capacity DWDM systems.

Core values and positioning:

Capacity multiplier: Combine 40 wavelengths into one transmission, increase single fiber capacity by 40 times, and maximize fiber spectrum utilization.

Zero power consumption and high reliability: completely passive design, no power consumption, no heat generation, with extremely high reliability and long service life.

Application suggestion:

This board is the standard multiplexing component of the OSN 9800 wavelength division system, widely used in scenarios such as terminal stations and OADM nodes that require multiplexing. During deployment, it is necessary to ensure that the channel spacing and wavelength range of the multiplexing board and demultiplexing board match, and to connect the optical performance monitoring unit using the MON port (if configured) to construct a visualized intelligent optical layer. When used in conjunction with TN11D40 (demultiplexing board), it can form a complete 40 wave DWDM transceiver system.
