OCN-Q8

1. What is the primary function of the cladding in a step-index fiber?

• A) To increase the fiber's core diameter

• B) To reduce the light loss by reflecting light back into the core

• C) To increase the refractive index of the fiber

• D) To prevent external physical damage to the core

2. In a step-index fiber, what is the typical refractive index profile of the core and cladding?

3. Which of the following is a major advantage of step-index fibers over graded-index fibers?

• A) Higher bandwidth

• B) Greater core diameter

• C) Simpler manufacturing process

• D) Better modal dispersion

4. What happens to the light traveling through the core of a step-index fiber?

• A) It gets absorbed by the cladding

• B) It reflects off the core-cladding interface and remains within the core

• C) It scatters within the core

• D) It escapes through the cladding

5. 5.What is the typical use case for step-index fibers?

• A) High-speed data transmission over short distances

• B) Long-distance telecommunication
