What is the primary function of a splice closure in fiber-optic installations?

The primary function of a splice closure in fiber-optic installations is to protect optical fibers and splices from environmental changes. Splice closures are designed to create a safe and secure environment for fiber splices, which can be vulnerable to moisture, dust, and mechanical stress. By ensuring that these splices are safeguarded from environmental threats, splice closures help maintain the integrity of the fiber-optic network, preventing issues such as signal loss or degradation that could arise from exposure to the elements.

The robust, weatherproof design of splice closures is essential for long-term performance and reliability, especially in outdoor installations where climate conditions can vary greatly. This protection is crucial for ensuring that the optical signals remain strong and that the overall system functions as intended over time.
