Does anybody experience wavelenth deviation due to LSR_WILL_DIE alarm in OTU board in OSN6800?

I experienced this few months ago?

Anyone who knows this ?

This alarm appears when the laser of an OTU it?s faulty, the impact on the service is that the transmitted power or the wave form deteriorates so at the receiving end the lambda can?t be detected correctly. The only way to solve this issue is replacing the OTU in case the interface is fixed, or replace SFP in the case it?s a pluggable module.

Dear sevillaf, yes the only way to resolve it by replacing board. I solved in this way.

Great share, thank you~

Good piece of info

Good knowledge sharing, keep an eye on electrical power variations of the equipment room, as it may inflict LASER_WILL_DIE alarm.
