Fiber optic closures are used to protect and manage the connections of fiber optic cables in various environments such as underground, aerial, and submarine. They are typically used in telecommunications networks and other applications that require high-speed data transmission over long distances.

Advantages of fiber optic closures include:

High bandwidth capacity: Fiber optic cables have a much higher bandwidth capacity than traditional copper cables, allowing for faster data transfer rates.

Immunity to electromagnetic interference: Fiber optic cables do not conduct electricity and are not affected by electromagnetic interference, making them more reliable for data transmission.

Durability: Fiber optic closures are designed to protect fiber optic connections and cables from environmental factors such as water, dust, and temperature changes, ensuring a long service life.

Easy to install: Fiber optic closures are relatively easy to install and can be used in a variety of settings, including underground, aerial, and submarine.

Scalability: Fiber optic closures can be easily expanded to accommodate additional fiber optic cables as needed, making them a flexible solution for growing networks.
