TNG2ADC0824 Add and drop unit with contentionless function.
As a type of wavelength selective switching board, the DWSS20 board is used with the optical multiplexer and demultiplexer unit and optical add and drop multiplexing unit to implement wavelength grooming at the nodes in the DWDM network.
- Add any combination of wavelengths through any of the following optical interfaces: AM01 – AM20.
- Drop any combination of wavelengths through any of the following optical interfaces: DM01 – DM20.
|WDM specification||Supports the DWDM specifications.|
|Gain locking technology||Not supported|
|Online optical performance monitoring||Provides an online monitoring optical port (MON). Through this optical port, a small number of optical signals can be output to an optical spectrum analyzer or an optical spectrum analyzer board. In this manner, the spectrum and optical performance of the multiplexed optical signals can be monitored without interrupting services.
The online optical performance monitoring function can be used only for temporary optical performance monitoring when the MONI/MONO power meets the power detection range of the detection instrument or spectrum analysis board. For details about long-term monitoring, see the application scenarios of spectrum analysis boards.
|Optical power adjustment||Supports power adjustment for each wavelength.|
|Multiplexing of the main optical path and supervisory signals||Not supported|
|Loopback||Supports optical-layer loopbacks.|
|Alarm and performance event monitoring||Detects the optical power and reports the alarms and performance events for the board.|
