A fiber optic closure is a device used to provide space for optical fibers to be spliced together. It also protects the spliced fiber and joint parts from hostile environments. The design of the closure varies depending on application areas. It is crucial to figure out the cable compatibility before selecting the right type of closure for your network.

Spliced fibers are vulnerable to many dangers, such as extreme temperatures, moisture and even bugs. Closures are small boxes that help to protect the spliced areas of your fiber-optic networks. Choosing the right one for your network is vital to ensure it will function correctly and efficiently.

There are several different models of fiber optic closures available on the market, each with different capacities and configurations. For example, dome fiber closures often feature high-levels of seals and waterproof technology due to their underground applications. There are also vertical fiber optic closures that can be mounted aerially, duct or direct buried. Whether you choose a horizontal or vertical model, the capacity of your closure will depend on how many splice trays it has and its overall size. You should also consider the type of splice you’ll use, as ribbon and mechanical splices can reduce the capacity of the splice tray. Additionally, the splice tray should have a configuration that helps to improve cable performance without twisting or stressing the cables.
