wavelength
To set the wavelength on a DWDM controller to a specific ITU channel or to define a specific frequency or
wavelength to a DWDM controller, use the
wavelength
command in DWDM configuration mode. To return
the wavelength to its default value, use the
no
form of this command.

Syntax Description
Specifies 50-GHz frequency grid.
50GHz-grid
Specifies 100-GHz frequency grid.
100MHz-grid
ITU channel number. ITU channel numbers have predefined frequencies as
defined by Multi Source Agreement (MSA) International Telecommunication
Union (ITU) grid.
•
The range is 1 to 100 for conventional band (C-band)
channel-number
Keyword that specifies the frequency for the DWDM controller.
Enter the 5-digit frequency value in the range of 19115 to 19610 GHz. For
example, enter
frequency 19580
to specify 195.8 THz.
frequency frequency
Keyword that defines a specific wavelength for the DWDM controller.
Enter the 7-digit frequency value in the range of 1528773-1563863 micrometers
(mm). For example, enter
update 1532290
to specifiy 1532.29 nanometers (nm).
