Also software bug? Got any other devices with these transceivers on
this software version working OK?

You said you tried a difference transceiver but it was the same
make/model from the same manufacturer right? If it’s an
incompatibility issue (unlikely) then it would still be present.

The cross-connect is the same, is someone shutting you fibre in the
door periodically? I not sure why you would get -40dBm on Tx unless
you have a transceiver failure or total internal reflection.
