What type of splicing module is preferred for free breathing space in aerial applications?

The encapsulated splicing module is preferred for free breathing space in aerial applications due to its design and protective features. This type of module is typically sealed within a durable enclosure that protects the splices from environmental factors such as moisture, dust, and physical impacts. This is particularly essential in aerial installations, where the risk of exposure to the elements is higher than in underground or more protected environments.

Encapsulated modules provide a controlled environment for the fiber splices, ensuring that they remain free from contaminants and potential damage caused by vibration or extreme weather conditions. The encapsulated design also allows for thermal and mechanical stability, which is crucial in aerial applications where temperature variations can be significant.

In contrast, other types of splicing modules, such as exposed or heat-shrink types, may not offer the same level of protection against environmental hazards, making them less suitable for aerial deployments. Standard modules may lack the specific encapsulated features needed to ensure optimal performance and longevity in outdoor applications.
