The application of M40V single board in WDM system is shown in Figure 1.
Figure 1 Application of M40V single board in WDM system
The M40V single board supports functions and features such as multiplexing, online optical power monitoring, alarm and performance monitoring, and optical power adjustment.
The specific functions and features of the M40V single board are shown in Table 1.
| Functions and Features | Description |
|---|---|
| Basic Functions |
Realizes multiplexing up to 40 single-wavelength optical signals into 1 combined-wavelength optical signal, and can adjust the input optical power of each channel.
|
| Online Optical Power Monitoring |
Provides an online monitoring optical port from which a small amount of optical signals can be output to a spectrum analyzer or a spectrum analyzer board to monitor the spectral and optical performance of the combined-wave optical signals without interrupting the service. |
| Alarm and Performance Monitoring |
Provide optical power detection function and single-board alarm and performance event reporting function. |
| Optical power adjustment function |
Provide optical power adjustment function for each single wavelength of optical signal before combining. Description:
The TN13M40V veneer board supports the optical power adjustment function only when combined with the optical power intelligent equalization system software License. If there is no optical power intelligent equalization system software License, TN13M40V single board can only be used as M40 single board. |
| Optical Layer ASON | Support |
The single-board specifications include optical interface specifications, single-board size, weight, and power consumption.
| Item | Unit | Indicator |
|---|---|---|
| Channel spacing | GHz | 100 |
| Insertion Loss | dB | ≤8a |
| Reflection Coefficient | dB | <-40 |
| Working wavelength range | nm | 1529～1561 |
| Adjacent channel isolation | dB | >22 |
| Non-adjacent channel isolation | dB | >25 |
| Attenuation Range | dB | 0 to 15 |
| Attenuation accuracy | dB | ≤1 (0～10dB) |
| dB | ≤1.5 (>10dB) | |
| Polarization-related loss | dB | ≤0.5 |
| Maximum difference in insertion loss of each channel | dB | ≤3a |
| a: When the VOA value is set to 0dB attenuation, it contains the intrinsic insertion loss of MUX and VOA. Description: TN13M40V supports the built-in VOA function only when combined with the optical power intelligent equalization system software License. Without the Optical Power Intelligent Equalization System Software License, the TN13M40V veneer can only be used as an M40 veneer. |
