Hello!
Well, with the assumption that you have tried all the obvious things, it seems that you need to look for the "longshot" possibilities.
Do you have an AC power supply at the node location by chance? The reason I ask is because I have encountered what you are speaking of in the past.
I found that the "hot" AC wire that was going to the "gooseneck" that fed the AC supply very close to a house drop. The bozo who wired up the supply had the electrical wires within inches of the strand and house drops. The supply and node were at the same pole. Unfortunately the AC potential and ground was energized and radiation bled over onto the strand and into the reverse laser. I had to physically move the AC electrical wires further away from the strand/cable/drops until it dissapeared.
I hope that this possibility has helped. Give me a call on cellular. Might have more ideas after a good night sleep...lol.
Good luck!

> Having problems with an elevated noise floor during ingress tests for certification. Using SG200 nodes. The noise floor is elevated about 6 db with a reverse tilt. Have changed all node components, switched fibers, checked return balance, changed receiver at hub and pulled forward and return rf. The only thing that drops the noise floor is to pull light. No ingress on node. Help!
