How are optical splices held in place within a splice tray?

Optical splices are held in place within a splice tray primarily through the use of retaining clips. These clips are designed to secure the optical fibers and ensure that the spliced connections remain stable and protected from movement or damage. The retaining clips typically provide a firm grip around the splice while allowing for some flexibility, which is essential in managing the delicate nature of optical fibers.

Using retaining clips is advantageous as they ensure that the splices are easily accessible for maintenance and inspection, while also allowing for organized routing of the fibers within the tray. This organizational method helps prevent excessive bending or stress on the fibers, promoting longevity and reliability in the connections. Additionally, while other methods like adhesive or locking mechanisms can provide stability, retaining clips are specifically designed for easy insertion and removal, making them the preferred method in splice tray designs.
