Use this procedure to configure the transmit power for trunk (CIM8 and PICO) optics within a defined range to optimize optical signal performance.
Use this task to configure transmit power on the trunk (CIM8 and PICO) optics within the -190 to +50 range (in units of 0.1dBm)
Procedure
Enter the
controller optics command in the global configuration mode.
Example:
RP/0/RP0/CPU0:ios#configure
Mon Aug 19 19:31:42.115 UTC
RP/0/RP0/CPU0:ios(config)#controller optics 0/1/0/7
RP/0/RP0/CPU0:ios(config-Optics)#transmit-power -1.50
RP/0/RP0/CPU0:ios(config-Optics)#commit
Mon Aug 19 19:35:24.697 UTC
RP/0/RP0/CPU0:ios(config-Optics)#exit
RP/0/RP0/CPU0:ios(config)#exit
This is a sample in which transmit power of -1.50 dBm is configured on the CIM8 optics.
