When clean fiber optic connectors are undisturbed the optical path can be preserved for years. However, during installation, maintenance, reconfigurations and equipment upgrades, those pristine connector end-faces often are exposed to the environmentand the end-face may become contaminated. It’s been estimated that connection points are the source of about 70% of the optical network failures, and 70% of those failures are a result of simple contamination of the end-face. The author explores better ways to clean and inspect fiber end-faces, saving time and money in the process.
