The DWSS20 board supports dynamic wavelength grooming, and in-service monitoring of performance parameters, performance events, and alarms.
For detailed functions and features, refer to Table 1.
| Function and Feature | Description | ||
|---|---|---|---|
| Basic function | Implements optical-layer service grooming for multiple wavelengths. Wavelength adding: adds any wavelengths from any directions through ports AM1 to AM20 and outputs the wavelengths through the OUT port. Wavelength dropping: receives optical signals from the main path through the IN port, drops wavelengths to any directions, and outputs them through ports DM1 to DM20. Adjusts single-wavelength attenuation in the wavelength adding and dropping directions. | ||
| WDM specification | Supports the DWDM specification. | ||
| Spectrum application | Supports flexible grid wavelength signals. The signals have continuous n x slice GHz spectrums (one slice is equal to 12.5 GHz, and n is an integer ranging from 3 to 32) to meet the bandwidth requirements of high-rate services. When multi-rate services are transmitted together, Gridless flexibly allocates bandwidth to improve the bandwidth utilization efficiency. This function requires the WSS Flexible Grid Tunable Function license. | ||
| 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 any add wavelengths at the local station. | ||
| Optical-layer ASON | Supported | ||
Specifications include optical specifications, dimensions, weight, and power consumption.
