What are splice closures primarily designed to protect against?

Splice closures are primarily designed to protect against environmental changes in aerial and underground installations. These closures serve as protective enclosures for fiber optic or telecommunications splice points, ensuring that the delicate connections made during splicing remain safe from various environmental factors.

In aerial installations, splice closures guard against elements such as moisture, temperature fluctuations, wind, and debris, which could potentially compromise the integrity of the splices. Similarly, in underground settings, closures protect against soil pressure, water ingress, and temperature extremes which can adversely affect the performance of the splice points. The robust nature of these closures is crucial in maintaining connectivity and preventing issues that can arise from exposure to elements.

While other factors, like physical damage during transport or electrical interference, are important considerations in the overall management of telecommunications infrastructure, the primary function of splice closures is centered on environmental protection. This ensures long-term reliability and performance of the splice connections, reducing the risk of outages or degradation in service quality.
