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.
Table 1 Functions and features of the DWSS20 board
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.
