We have used pigtails fusion spliced at the customer end. Didn’t have much luck with mechanicals, mostly because we struggled with getting them to work reliably at the office.
The Sumitomo Quantum Handheld fusion splicer isn’t real expensive and works very well. We have had few issues with it using it daily for splicing pigtails at customer houses. Clean it occasionally and it does just fine. As far as testing - plug in the OLT and see what the reported signal levels are. Compare them with the acceptable levels and the number on the other customers on that ONT port. If signals out of line first clean the connectors, then break out the optical power meter and check at the NID to see it the issue is inside or outside. If it’s outside check and clean the connector at the pole/handhole if there is one. If you still can’t find it you can break out the OTDR, though keep in mind the OTDR probably isn’t going to tell you much about the pigtail. It’s very difficult to see much of interest on an OTDR near the launch point, and it’s hard to see anything when the pigtail splice is 3’ from the pigtail end. Probably easier to just replace the pigtail if you think the splice might be screwed up.
