Absolutely. Probably just a bad splice.

Yes, and depending on the length of the fiber and the conditions on the other
end, you can have a return loss effect causing a splice to appear to have
negative loss. Called a “gainer“. But this trace looks like a bad splice to
me.

When we found issues in our fiber, it has always been bad bends. We have
Sumitomo splicers and they've all been flawless so far. Just our
experience.
Our OTDR is cheap china junk - it can't actually detect the splices ~90% of
the time. Veex demo units caught every single splice.
