On a cross section of a fiber optic cable. Name and explain the parts & the role played by each part.- core- cladding- outer jacket coating

Core: The core is the innermost part of the fiber optic cable and it is where the light signals are transmitted. It is made from a glass or plastic material that has a high refractive index. The diameter of the core determines the amount of light that can be transmitted and the distance it can travel.

Cladding: The cladding surrounds the core and is also made from a glass or plastic material, but it has a lower refractive index. The role of the cladding is to keep the light signals contained within the core by causing total internal reflection. This ensures that the light signals can travel long distances without losing too much strength.

Outer Jacket Coating: The outer jacket coating is the outermost layer of the fiber optic cable. It is usually made from a durable plastic material and its main role is to protect the inner parts of the cable (the core and the cladding) from physical damage and environmental factors such as moisture and temperature changes. It also provides a degree of flexibility to the cable, allowing it to be bent and routed around corners without damaging the inner parts.
