Chapter 18.1, Problem 11SSC

To determine

Type of glass used for cladding in optical fiber.

Explanation of Solution

Introduction:

Cladding:

Middle layer of an optical fiber is known as cladding.

Core:

Innermost region of an optical fiber is known as core.

To make cladding region of an optical fiber, float glass is used because refractive index of float glass is less than cladding material due to which total internal reflection can take place in core region.

Conclusion: The type of glass isfloat glass because refractive index of float glass is less than core material.
