The core of a fiber cable can best be described as a cylinder of plastic which runs along the fiber cable’s length. It, however, gives protection by means of covering. The width of the Core generally depends on the application that is being used. As a result of internal reflection, the travelling of light that is within the core mull over from the core, to the cladding boundary. The core cross section, however, requires to be in a circular form for most of the applications.


The Cladding can be described as an outer optical material which serve as a protector for the core. The main function of cladding is that, it goes as far as reflecting the light transmitted back into the core. When the light flux through the core or better still the dense material into the cladding which is, the less dense material, it will alternate its angle, and then reflects back on the core.


The function of a buffer is used to serve as a protection for the fiber from hazard like damage, and also there are thousands of optical fibers that are positioned in hundreds of optical cables. Essentially, these bundles serve as a protector of the cable’s outer covering which is better called a jacket.


The Fiber optic cable’s jackets can be seen in various colors, and can easily enable us know the precise color of cable that we are making use of. However, the famous color yellow signifies clearly as a single mode cable, and also the orange color pinpoint a Multimode.
