Provides step-by-step instruction on how to complete each fiber optic task. Enhanced with high quality graphics. In the past, the purpose of cleaning fiber optic connectors was to prevent damage to the fiber during mating of the fiber ends to each other. However, today's more advanced and faster transmission systems that use higher power lasers require even more attention to the cleaning of the connection surfaces. Reviews the products, applications, and their proper usage. It shows the causes of contamination when using various cleaning techniques and demonstrates the different products used to clean: fibers, connector end faces, and cleaning sleeves and mated connector parts.
