Validate 400ZR optics report module level internally measured temperature in 1/256 degree Celsius increments as defined in the CMIS.

-
Connect two ZR optics using a duplex LC fiber jumper such that TX output power of one is the RX input power of the other module.
-
To establish a point to point ZR link ensure the following:
- Both transceivers state is enabled.
- Both transceivers are set to a valid target TX output power example -10 dBm.
- Both transceivers are tuned to a valid centre frequency example 193.1 THz.
-
With the ZR link established as explained above, verify that the following ZR transceiver telemetry paths exist and are streamed for both the ZR optics.
- /platform/components/component/state/temperature/instant
- /platform/components/component/state/temperature/min
- /platform/components/component/state/temperature/max
- /platform/components/component/state/temperature/avg
-
For reported data check for validity min <= avg/instant <= max
-
If the modules or the devices are in a boot stage, they must not stream any invalid string values like "nil" or "-inf".
-
Reported temperature value must always be of type decimal64.
Note: For min, max, and avg values, 10 second sampling is preferred. If the min, max average values or the 10 seconds sampling is not supported, the sampling interval used must be specified and this must be captured by adding a deviation to the test.
-
Verify the module temperature is reported correctly with optics interface in disabled state.
-
Use /interfaces/interface/config/enabled to disable the interfaces and wait 120 seconds(cooling off period) before taking the temperature reading again.
-
Verify the module is able to stream the temperature data in this state.
-
Verify the module reported temperature in this state is always less than the module temperature captured during steady state operation with interface state enabled.
-
For reported data check for validity min <= avg/instant <= max
-
If the modules or the devices are in a boot stage, they must not stream any invalid string values like "nil" or "-inf".
-
Reported temperature value must always be of type decimal64.
