It’s a 1x2 PLC, and I wondered if it could have been an unterminated leg, but usually you get noise after a dead end whereas this trace continued on for a bit before hitting a definite dead end.

It all depends on the type of splitter you are using and what wavelength the OTDR is. It also depends what is on the other ends of the splitter. If that is a splitter with nothing spliced to one of the ends you can get a reflection off of a dead end.

It's supposed to be fusion spliced, not connectorized. There are several of these on this project. Trying to figure out if contractor snuck in some incorrect parts or if he's got issues with his fusion splicer. I'd assume it's bad splices, but maybe coincidentally the reflectance just happens to be about right for UPC connectors.
