Optical Add and Drop Multiplex Board

In this user interface, you can set and query the added/dropped wavelengths for optical add and drop multiplex boards.

Parameters

Field	Value	Description
Optical Interface/Channel	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)	Displays the position of this optical interface.
Optical Interface Name	For example: A1/D1	Displays default names. Do not modify this field.
Gridless Optical Interface Attenuation Ratio (dB)	Value of Min. Attenuation Rate (dB) to Value of Max. Attenuation Rate (dB), Blocking, /	Specifies the attenuation for the optical interface. This parameter ensures that the launch power of the transmit end complies with the system power requirements. Before the commissioning, the attenuation ratio of each channel must be preset. When no optical cross-connections are present, the parameter value is displayed as /. When NE-level optical cross-connections are present or when the end-to-end configuration function is used to configure optical cross-connections and OPA Mode is set to Manual, the parameter value is displayed as Blocking after an OCh trail is created. If you set the parameter at this time, the specified value is then displayed. The attenuation adjustment amplitude should not be very large. It should be controlled within ± 2 dB compared with the original attenuation every time the attenuation is adjusted in a new project. During the expansion of a project or during maintenance, however, the attenuation adjustment amplitude should be controlled within ± 0.5 dB compared with the original attenuation when the attenuation is adjusted. To obtain the value range of this parameter, query the value of the Min. Attenuation Rate (dB) and Max. Attenuation Rate (dB) parameters.
Gridless Attenuation difference (dB)	-3 to 3, with a step of 0.1 Default: none	Sets the relative optical power attenuation of a board channel. When using this parameter with Attenuation (dB), you can adjust optical power attenuation of a board channel more accurately. If Optical Interface Attenuation Ratio (dB) is set to 9 dB and Attenuation Difference (dB) is set to 1.5 dB, then the attenuation of the optical interface is 10.5 dB.
Gridless Max. Attenuation Rate (dB)	-	Displays the maximum attenuation allowed by a board optical interface.
Gridless Min. Attenuation Rate (dB)	-	Displays the minimum attenuation allowed by a board optical interface.
Actual Wavelength No./Add-Drop Wavelength (nm)/Frequency (THz)	For example: 1/1529.56/196.000	Queries the added/dropped wavelength of the board. It is applicable to CMR2 and CMR4.
Actual Band Type	C, CWDM	Queries the actual waveband type.
Configure Wavelength No./Add-Drop Wavelength (nm)/Frequency (THz)	For example: 1/1529.56/196.000	Configures the added/dropped wavelength of the board.
Configure Band Type	C, CWDM	Configures the waveband type of the board.
Actual Working Band Parity	Odd, Even, All	Displays the parity of the actual working band.
Configure Working Band Parity	Odd, Even, All	Sets the parity of the working band.
Board Mode	Bandpass mode, OADM mode	Sets the mode for an MR1 board.

NOTE:

In the case of different boards on different equipment, different WDM interfaces are supported. According to the corresponding user interface of the NMS, the parameter description table lists the whole set of parameters in this user interface of the NMS. For detailed parameters supported by each board, see the Hardware Description for each type of equipment.
