What method is used to secure optical splices in a splice tray?

The method used to secure optical splices in a splice tray is cable (retaining) clips. These clips are specifically designed to hold the optical fibers and splices securely in place, ensuring that they are protected from movement or strain that could lead to damage or signal loss. The use of retaining clips provides a stable and organized environment for the fiber splices, which is essential for maintaining the integrity of the optical network.

In the context of fiber optic installations, ensuring that the splices are not only secure but also easily accessible for future maintenance is crucial. Retaining clips offer a practical solution that facilitates this by allowing for easy adjustments without compromising the protection of the splices.

While other options such as heat shrink tubing, adhesive bonding, or Velcro strips have their applications in fiber management, they do not provide the same level of stability and accessibility as cable clips when it comes to splice trays. Heat shrink tubing typically protects individual fiber sections rather than securing them in place, adhesive bonding is more permanent and limits future adjustments, and Velcro strips may not provide the necessary hold for the precision required in fiber optic work.
