To avoid contaminating the fiber optic cables, you should keep the work surfaces as clean as possible. Just like with the cables, you should clean the surfaces using the dry cleaning method. You should use the wet cleaning method as the last resort. This is to minimize the risk of contaminating your optic cables due to the presence of excess alcohol on the surfaces. In addition to keeping your working surfaces clean you should also keep them organized. You should use resealable containers to keep all of your cleaning tools and end caps.
These are the areas that you should pay attention to when you are cleaning your optic cables. When you are inspecting the cables for dirt remember to turn off the laser sources in order to avoid damaging your eyes. Also, ensure that the cable is disconnected at both ends before you do the inspection.
