For checking transmission links on Cisco Routers, it is good to know how to find out the optical power of 100GE modules or interfaces for troubleshooting and making sure the desired or optimal range is meet. Here are the sample commands for checking the Transmit/Output (TX)  and Receive/Input (RX) optical power. show interfaces diagnostics optics <interface-name> Sample Output: fnt@JUNIPER-ROUTER1-re0> show interfaces diagnostics optics et-0/0/0 Physical interface: et-0/0/0 Module temperature : 28 degrees C / 82 degrees F Module voltage :…
