What is the main use of loose-tube fiber-optic cable?

Loose-tube fiber-optic cable is primarily designed for long-distance communication and is often used as the main cable between the headend and node in a fiber-optic network. This type of cable accommodates multiple optical fibers encapsulated in separate tubes, allowing for a flexible design that provides protection against environmental factors, such as temperature and moisture. The loose-tube design also prevents strain on the fibers, which is crucial when considering the need for long, uninterrupted runs of cable that are typical in backbone installations.

In contrast to other types of cables, loose-tube fiber is well-suited for outdoor installations and is ideal for connecting fiber optic systems across significant distances. Therefore, its main use in linking headend facilities to distribution nodes truly highlights its role in supporting the infrastructure essential for broadband communication and data transmission over extensive geographical areas.
