What type of installations typically require splice closures?

splice closures are essential components used primarily in optical fiber networks. These closures provide a secure, protective environment for the splicing of optical fibers, which is necessary to join two fibers together to ensure continuous signal transmission. The use of splice closures in optical networks helps to maintain the integrity of the fiber connections while also preventing environmental factors such as moisture, dust, and mechanical stress from damaging the splices.

In contrast, residential wiring and electrical power systems generally do not utilize splice closures, as these installations typically involve solid conductor connections that do not require the same level of protection or environmental sealing as fiber optic splices. Telecommunication services may involve some form of splicing, but it is the specific context of optical fiber networks that typically necessitates the specialized use of splice closures for optimal performance and durability.
