  1. Maintenance of fiber optic connectors New York. 2007

  2. Maintenance & repair concepts/ issues • Fiber optic contacts need to be inspected and kept clean, just like a camera lens • Maintenance is simple process of regular inspection & cleaning when necessary. • Fusion Splicing can be a cost effect and quick process for field solutions when accidents happen. • Did I mention Fibre optic contacts need to be inspected and kept clean, just like a camera lens? • REPLACE THE CAPS! • There is no replacement for care and cable awareness. Maintenance and repair of cable / connector infrastructure is of primary concern to users. New York. 2007

  3. Inspection • For reliable operation of the system it is essential for the ferrule end faces of any fiber optic contact to be clean and free from any debris • It is strongly recommended that ferrule end faces are regularly inspected by using commercially available video inspection microscope e.g. Lightel. FIS. • Essential to clean contacts on both sides of a mated pair if one is dirty. New York. 2007

  4. Cleaning Procedures The Process • Cleaning the LEMO contact is very simple using cotton buds. • If necessary, remove alignment sleeve using removal tool. • Clean ferrule end face using one cotton bud soaked in Isopropyl Alcohol, or Fiber Cleaning Fluid then dry the end face using a second dry cotton bud. • If alignment sleeve has been removed, replace the alignment sleeve. Note: It must “click” home. • Blister pack buds are pre-soaked • NOTE: Alignment sleeve is retained on the tool throughout the process, so it cannot become lost or contaminated. • 2 other common methods - FerruleMate and Aefos AFC3000. Useful for emergencies/OB use. • If such tools used, regular maintenance using cotton buds still recommended New York. 2007

  6. Maintenance procedures Conclusions • A good cleaning process is essential for the correct performance of any fiber optic system • The use of an inspection scope is vital to determine if cleaning is needed – Rule is “if your disconnect it, clean it” • Proprietary cleaners are available but produce mixed results. • The best (and lowest cost) solution is still the use of Cotton buds and Isopropyl alcohol or a Fiber Cleaning Fluid. • Remember: If the alignment device has been removed during the cleaning process it must be replaced and “clicked” home.
