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 :…

Fiber Optic Transceivers are wavelength-specific lasers that can convert electrical data signals into optical signals via optical fiber. It is basically a device that uses fiber optical technology in sending and receiving data. Here’s the classifications: Based on form factors 1. XENPAK – original 10G pluggable optics using SC connector type 2. X2 -provides 10G connectivity up to 40km on SMF and successor of XENPAK. Also used SC connectors 3. GBIC -short for Gigabit Interface Converter, is a standard…
Why is considered hidden? Because you won’t see it in the command in Cisco Routers Command Line Interface (CLI). Sample output: RP/0/RSP1/CPU0:CORE1#ser? service RP/0/RSP1/CPU0:CORE1#service ? redundancy Service Director related commands. Then what it is? service unsupported-transceiver Configuration: Cisco IOS-XE Router1(config)#service unsupported-transceiver Warning: When Cisco determines that a fault or defect can be traced to the use of third-party transceivers installed by a customer or reseller, then, at Cisco’s discretion, Cisco may withhold support under warranty or a Cisco support…
