Tunable DWDM-XFP-C Tuning by Wavelength in Cisco

Posted at February 23, 2018 in by

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.

{ wavelength channel-number | frequency | update }
{ no wavelength channel-number | frequency | update }

The following example shows how to set the DWDM wavelength to ITU channel 10.

RP/0/RP0/CPU0:router(config)# controller dwdm 0/1/0/0
RP/0/RP0/CPU0:router(config-dwdm)# wavelength 10

The following example shows how to set the frequency of ITU channel 10 to 195.8 THz.

RP/0/RP0/CPU0:router(config)# controller dwdm 0/1/0/0
RP/0/RP0/CPU0:router(config-dwdm)# wavelength 10 frequency 19580

 

The following example shows how to set the wavelength of ITU channel 10 to 1532.29 nm.

RP/0/RP0/CPU0:router(config)# controller dwdm 0/1/0/0
RP/0/RP0/CPU0:router(config-dwdm)# wavelength 10 update 1532290
