Precision Rated Optics offer several cleaning Go-Kits at incremental price points and inclusions. Get just the basics or upgrade for more! Inspect, Clean, Evaluate.. Test (ICE-T). Always inspect your endface to determine its quality or the type of contaminates in order to choose the preferred cleaning method. After cleaning with either dry or wet methods, evaluate your cleaning with either a hand-held inspection scope or a video inspection probe. Repeat the process if necessary. When your endface is clean, go ahead and connect to your test equipment! Remember that most network failures are due to improper cleaning and inspection. Prevent most link problems before they start!
