Question

Multimode graded index fibers are manufactured from materials with ______.

• A. Lower purity
• B. Higher purity than multimode step index fibers
• C. No impurity
• D. Impurity as same as multimode step index fibers

Hint:

Graded index fibers are made from high-purity materials to improve transmission efficiency by minimizing signal loss.

Answer 1

The Correct Option is B

Step 1: Understand graded index fibers.
Graded index fibers have a varying refractive index that decreases from the center to the outer part of the fiber.
These fibers are used to improve signal transmission.
Step 2: Purity of the material.
Multimode graded index fibers are typically made from materials with higher purity than multimode step index fibers.
The higher purity reduces attenuation and increases signal clarity over longer distances.
