How is a splice closure used?

A splice closure is specifically designed to protect and house fiber optic splices, particularly in outdoor settings. This is crucial because splices are vulnerable to environmental factors such as moisture, temperature fluctuations, and physical stress. The closure creates a sealed environment that safeguards the delicate spliced fibers from these harmful elements, ensuring reliable performance and longevity of the connection.

Furthermore, while storing excess fiber cable or serving as a connection point for multiple fibers may seem relevant, the primary function of a splice closure is to protect the splices themselves. It does not enhance signal strength, as that is typically achieved through other means, such as the use of optical amplifiers or repeaters. Thus, understanding the specific purpose of a splice closure clarifies its essential role in fiber optic installations.
