What practice minimizes water intrusion during installation?

Utilizing sealed closures is essential for minimizing water intrusion during installation. Sealed closures are designed to create a waterproof barrier around the fiber optic splices and connections. This protection helps prevent moisture from entering the enclosure, which could lead to corrosion of metal parts or degradation of the fiber itself over time.

A well-sealed closure not only guards against water but also protects against other environmental factors such as dust and debris, maximizing the longevity and reliability of the fiber optic system. In environments where water exposure is common, such as underground or in harsh weather conditions, sealed closures become even more critical to ensure the integrity of the system.

While other practices, such as implementing regular inspections, can help identify existing issues or potential vulnerabilities, they do not prevent water intrusion at the time of installation. Installing above ground can reduce exposure to water but does not completely eliminate the risk in all situations. Open junctions, on the other hand, are inherently more susceptible to water intrusion as they lack the protective housing that sealed closures provide.
