50 Appendix C Handling and cleaning fiber optic equipment
212257-B
Frequent overstressing of fiber optic cable causes progressive degeneration that
leads to failure.
If you suspect damage to a fiber optic cable, either due to mishandling or an
abnormally high error rate observed in one direction, reverse the cable pairs. If the
high error rate appears in the other direction, replace the cable.
Tools and Materials
You need the following tools and materials to clean fiber optic connectors.
• Lint-free, non-abrasive wiping cloths
• Cotton swabs, with a tightly wrapped and talcum-free tip
• Optical-grade isopropyl alcohol (IPA)
• Canned compressed gas with extension tube
Cleaning Fiber Optic Connectors
You must perform the following maintenance procedures to ensure that optical
fiber assemblies function properly. To prevent them from collecting dust, make
sure connectors are covered when not in use.
This section contains the following procedures for cleaning fiber optic assemblies:
• “Cleaning Single SC and FC Connectors” next
• “Cleaning Duplex SC Connectors” on page 52
• “Cleaning Receptacle or Duplex Devices” on page 53
Warning: To prevent oil contamination of connectors, do not use
commercial compressed air or house air in place of compressed gas.
Danger: To avoid getting debris in your eyes, wear safety glasses when
working with the canned air duster.
