Which type of cable is most commonly used in outdoor applications?

The most commonly used type of cable in outdoor applications is Loose Tube cable. This type of fiber optic cable is designed specifically for outdoor use because of its construction. Loose Tube cables have fibers that are housed within a protective tube that allows for movement due to temperature changes, preventing stress on the fibers. This design is particularly beneficial for outdoor environments where conditions can vary widely.

Additionally, Loose Tube cables typically contain moisture-resistant materials and may include gel or water-blocking features that protect the fibers from water ingress, which is essential in outdoor installations. These cables are often used in long-haul telecommunications and connectivity solutions because they can accommodate a larger number of fibers and are less likely to be affected by environmental factors.

In contrast, while other cable types may serve specific purposes in different contexts, they are generally less suited for the rigors of outdoor installation when considering factors such as environmental resistance and mechanical protection.
