However, it may not be suitable for high-speed and long-distance applications due to limitations in signal quality and bandwidth.
2. Tight-tube structure
The tight-tube structure of fiber optic cable is characterized by the use of a tight bundle of optical fibers inside a protective tube with fixed walls. The fibers are fixed to the tube walls and are protected against external forces and damage. The protective tube is typically made of high-quality materials, such as aluminum or plastic, to ensure durability and reliability.
The tight-tube structure is commonly used in long-distance and high-speed applications, as it provides better protection for the fibers and higher bandwidth capabilities. It is also more expensive than the loose-tube structure, but it is suitable for high-performance telecommunications systems that require reliable and long-lasting cables.
In summary, the two basic fiber optic cable structures are the loose-tube structure and the tight-tube structure. The loose-tube structure is suitable for short-distance and lower-bandwidth applications, while the tight-tube structure is suitable for long-distance and high-speed applications. When purchasing fiber optic cables, it's essential to consider the type of cable, its specifications, quality, and compatibility with other equipment.
