Hello, my friend.
The WSM9 board is mainly used to dynamically groom wavelengths, monitor online optical performance, and monitor alarms and performance events.
For detailed functions and features, refer to Table 1.
Table 1 Functions and features of the WSM9 board
| Function and Feature | Description |
|---|
| Basic function | Configures any wavelengths to any interfaces. A node on the ring or chain network can receive any wavelengths at the local station through any interfaces to achieve the dynamic wavelength allocation. |
| WDM specification | Supports the DWDM specifications. |
| Spectrum application | TN11WSM9/TN12WSM9/TN17WSM9 Supports signals with a 100 GHz channel spacing. TN13WSM9 Supports signals with a 50 GHz channel spacing. TN16WSM9 Supports signals with a 50 GHz channel spacing. Supports flexible grid wavelength signals. The signals have continuous n x slice GHz spectrums (one slice is equal to 50 GHz, and n is an integer ranging from 1 to 8) to meet the bandwidth requirements of high-rate services. When multi-rate services are transmitted together, the board flexibly allocates bandwidth to improve the bandwidth utilization efficiency.
TN96WSM9 Supports extended C-band wavelengths Supports flexible grid wavelength signals. The signals have continuous n x slice GHz spectrums (one slice is equal to 12.5 GHz, and n = 3 to 32) to meet the bandwidth requirements of high-rate services. The board flexibly allocates bandwidth to improve the bandwidth utilization efficiency.

| Online optical performance monitoring | Provides an in-service monitoring port (MON). This port connects to an optical spectrum analyzer or spectrum analyzer unit to monitor the spectrum and optical performance of the multiplexed signal without affecting traffic. |
| Alarm and performance event monitoring | Detects the optical power and reports the alarms and performance events for the board. |
| Optical power adjustment | Provides the function to adjust the optical power of each channel. |
| Optical-layer ASON | Supported by the TN12WSM9/TN13WSM9/TN16WSM9/TN17WSM9/TN96WSM9. |
Thanks.
