I have seen this problem before the dialectric on the inside of the shield will cause a sukout effect on the high end no matter how tight the connector was. The way we did it was to use a tweaker and scrape out that thin layer it comes out easy, the time consuming part was figuring out which one was causing the problem. It was mainly on .540QR and it was so bad we had to make the splicers aware of the problem so we could get some production. Good Luck SB
