Structure of fiber optics cable
The same way as copper cables, fiber cables vary in specifications, mainly depending on the applications they are designed for. Variations might affect core diameter, materials used, and environment cable could be used in. In order to better understand how fiber cable works, one should have a look at its components (see Figure 1). When stripping optical fiber cable of its layers, following components can be observed:
- Outer jacket;
- Optional protection from physical damage;
- Strength members;
- Buffer;
- Optical fiber stand.
Each optical fiber stand has three components inside:
- Core;
- Cladding;
- Coating.
Size of the core is varying between 8 and 63 microns. Pieces of the strand are so tiny they can easily penetrate skin and in some cases travel through human body with blood vessels. This is one more reason why installation should be done by professionals using specially intended gear.
