A properly functioning fiber optic network requires clinical cleanliness of all fiber optic connections. A single
particle of dust or fingerprint can scatter enough optical power from the core to take down an entire link. While not in
use all fiber connector tips should be covered with dust caps to prevent damage such as scratches and pits from
forming on the connector ends. Pits and scratches on the surface of a connector can migrate when mated to
another connector consequentially spreading damage and requiring the re-termination on both fibers. To avoid
damaging fiber connectors Evertz recommends cleaning both ends of the fiber connection prior to mating using a
Cletop Reel as shown in Figure 16.
