Do you have an optical power meter? Or does the equipment you use have an optical received signal level parameter you can monitor? Any alarms or bad stats? I am sure a bad splice or splitter can cause problems like this but we have other numbers to help us prove it in the Calix equipment.
3 splitters are introducing 10-12 dB of loss. A full pon splitter (1:32) introduces about 16 dB of loss. So you don’t have too much splitter loss. Frequently you launch at –4 dBm and can go down into the –30 dBm range without problems. I would use a fiber microscope to look at the ends of the connectors. Use an OTDR to see if you can spot the problem. Do you have connectors at the splitters? Are you sure they are clean?

Got a situation with a Gpon deployment We are having throughput issues at one customer behind 3 plc splitters. We test after 2 splitters, all is good (900/900 mbps) after the 3rd splitter we can get our upload above 100-120 mbps… Would a bad splice or fusion cause this behavior?
