Multiplexer and Demultiplexer Board

In this user interface, you can set and query the attenuation rate of a port, the fixed band, and the parity of the working band.

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 optical interface.
Optical Interface Name	For example: OUT	Displays default names. Do not modify this field.
Optical Interface Attenuation Rate (dB)	For example: 20	Sets the actual attenuation ratio of the optical port.
Max. Attenuation Rate (dB)	For example: 40	Displays the maximum attenuation ratio allowed. When this ratio is exceeded, the output optical power is too low, causing the signal-to-noise ratio of the receive end to fall.
Min. Attenuation Rate (dB)	For example: 0	Displays the minimum attenuation ratio allowed. When this ratio is exceeded, the output optical power is too high, causing the signal-to-noise ratio of the receive end to fall.
Actual Band	C	Displays the actual working band of the multiplexer or demultiplexer board.
Configure Band	C	Displays the working band that you configure.
Input Power Loss Threshold (dBm)	-35.0 to -10.0	Input power that is smaller than this value cannot be determined.
Actual Working Band Parity	Even, Odd	Displays the parity of the current working band of the port. Currently only even band is supported.
Configure Working Band Parity	Even, Odd	Configures the parity of the current working band of the port. Currently only even band is supported.
PMD Coefficient (ps/SQRT(km))	0.00 to 1.00	Sets PMD coefficient.
Chromatic Dispersion Coefficient (ps/(nm*km))	-15.00 to 30.00	Sets chromatic dispersion coefficient.
Channel Number Mode	C40 Mode, C80 Mode, CWDM Mode	Sets and queries the channel number mode for the calculation of the resource utilization.
DCM Dispersion Compensation Direction	Send, Receive	Set DCM dispersion compensation direction.
DCM Dispersion Compensation Value (ps/nm)	1.0 to 6500.0	Set DCM dispersion compensation value.
