Periodic cleaning of the end faces of fiber optic cable links in aircraft avionics systems is undertaken as part of routine maintenance or when problems develop. Aeronautical Radio Incorporated (ARINC) has established guidelines for the installation and cleaning of fiber optic cables and components in its standards and a number of isopropyl alcohol based fiber optic cleaning kits are available on the commercial market. While these kits and techniques have proven successful in maintaining signal integrity over the short term, an industry standard as to the effects of repetitive cleaning operations has not been well established. The purpose of this study is to evaluate the effects of repeated end face cleaning on cable transmissivity and make this data available to the industry. It is anticipated the results will provide information useful to the overall determination of cable life cycles enhancing the safety and integrity of fiber optics usage in aircraft avionics systems.
