For something like GPON, looking at which customers are down will help get an idea if it's a power issue or fiber cut. Some customers have UPSes so that will help determine that.
If you really want to track fiber cuts, you can do a "loopback" at the far end of a fiber by allocating 2 lines to that purposes, tracking if the ethernet link passing through that loop ever goes down. There are SFPs with very limited built-in OTDRs but really you need to send a tech onsite to do anything useful.
