What is the purpose of splice trays within splice closures?

The purpose of splice trays within splice closures is to protect mechanical splices and store fiber slack. Splice trays are designed to securely hold the fibers after they have been spliced together, thereby safeguarding the integrity of the splices from external factors, such as moisture, dust, and physical stress that could disrupt the connection. Additionally, the trays provide a designated area to manage and organize the excess fiber, or slack, ensuring that it does not become tangled or damaged. This is crucial for maintaining the performance and longevity of the fiber optic network. The effective management and protection of both splices and slack contribute to a reliable and efficient fiber installation.
