Answer 2

The outer concentric shell in optical fiber is called the coating.

EXPLANATION.

• Optical fibers are used as a means to transmit light.
• The optical fibers are composed of three concentric elements, the core, the cladding, and the coating.
• The outer coating in the optical fiber is also called the buffer.
• Fiber optic core- The core is a part of the fiber that transmits light. The core is made up of silica or glass with a high refractive index.
• The cladding - Is the outer covering of the core, it has a slightly lower refractive index than the core.
• The coating - The coating is the protective covering of the optical fiber.
• It functions as a shock absorber to cladding and the core.
• Acrylate, silicon, carbon, and polyimide are some of the common materials for coating optical fibers.

Hence, The correct answer is Coating. #spj2
