Loose Tube Cables

Loose Tube Cables are a common type of fiber optic cable used to transmit optical signals. They get their name from the arrangement of the internal fiber optic cores, where the fibers are placed in a loose tube-like structure.

Loose tube cables typically include the following components:

1. fiber optic core: Inside is a set of fiber optic cores used to transmit optical signals. These fiber optic cores are usually placed in one or more loose tubular structures.
2. loose tube: a loose tube is a tubular structure in which the fiber optic cores are placed. This design allows the fiber optic core to move relatively freely to accommodate changes and stretching in the external environment.
3. Filling: To protect the fiber core and fill the space, the loose tube is usually filled with some special material such as absorbent gel.
4. Sheath: Loose tube cables usually have a sheath to protect the fiber optic core and the loose tube from the external environment.
