Question

MCQ - the inner core of an optical fibre in composition. ?

Answer 1

Answer:

The material used in the inner core of an optical fibre is a cylinder of glass or metal or plastic which runs through the length of the fibre.

Answer 2

Answer:

The inner core of an optical fiber consists, A clad that surrounds the low index core and contains light, a coating that protects the fragile fibers inside, and the core that carries the light is the smallest part of the optical fiber.

Explanation:

The inner core of an optical fiber is made of glass or plastic.

The thin core is surrounded by a jacket about $10$ times the diameter, a plastic outer coating (about twice the diameter of the jacket), reinforcing fibers made of durable materials like Kevlar®, and a protective outer jacket on the outside. It is.

Fiber optics are mainly made of silicon dioxide $(SiO _{2} )$ but for long-wavelength infrared and other special applications, small amounts of other materials such as fluorozilconate, fluoroaluminate, chalcogenide glass and sapphire. Crystalline material is used. Compounds such as  

It turns out that they can only be made of  glass, glass and polymers, or  polymers ("plastic fiber optics" POFs). The most basic optical fiber consists of: An inner cylinder with a high refractive index called the core. A central cylinder with a low index of refraction called the cladding.

A typical optical fiber consists of three main components. A clad that surrounds the low index core and contains light. A coating that protects the fragile fibers inside. The core that carries the light is the smallest part of the optical fiber.
