Hi. I recently buy a WAS-110 for XGS-PON Internet connection. I get something like 7Gbs with Orange ISP. But sometimes, once or twice a day, OpenWRT disconnect from internet with the logs:

WAS-110:

Mon Dec 23 09:56:18 2024 daemon.notice netifd: Interface 'lct' is now down
Mon Dec 23 09:56:18 2024 daemon.notice netifd: Interface 'lct' is disabled

Mon Dec 23 09:56:18 2024 daemon.notice netifd: Interface 'lct' has link connectivity loss

OpenWRT:

What can I do to avoid this?

Looking at the log, it would seem that the sfp module MOD-DEF0 (AKA Mod_ABS) is not hardwired to GND, but it is controlled by the microcontroller on the module.

Your log may indicate that the microcontroller is restarting.

A plausible cause would be overheating.
