How to check Tx power of a QSFP-40G-SR-BD or QSFP-40G-SR4 pluggable?

Hi!

We have some QSFP-40G-SR-BD or QSFP-40G-SR4 pluggable modules that installed in a 400G-XP card on a NCS 2006 shelf.

We already have unlocked service state of them but we can not show Tx power as below:

I plan to measure Tx optical power by OPM but I see no light (red light) in the Tx port as the same QSFP module that plugged in a Switch.

Please let me know to check Tx optical power via CTC or measure by OPM directly.
