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 :…

100G transceivers have been around for few years already and it is getting affordable since 2016 I guess, and it is now practical to shift to 100G instead of burning N x 10GEs. To see more info about 100G transmission principles, I find this link very informative -> https://community.fs.com/blog/understand-100g-transceivers-transmission-principles.html Here are sample 100G transceivers we deployed in our datacenters, it really depends on what type of vendor or hardware you have, but the most popular now is the QSFPs Juniper QSFP-100GBASE-LR4…
